Prof. Claus, Neurologist, was head of the Department of Neurology at the Hospital of Darmstadt in Germany. In his department approximately 5000 neurological inpatients were seen each year. Part of the department was a neurological intensive care unit and a stroke unit. In addition the department included a muscle section and clinics for epileptology, and movement disorders.
Neurologist, Prof. Claus, is certified in Epileptology, Neuroradiology, Rehabilitation Medicine, Clinical Geriatrics, Electroencephalography, Electromyography, Evoked potentials, Neurovascular ultrasound, and neuromuscular ultrasound. As neurologist he regularly lectures at the University of Heidelberg.
In 1990 he received the Richard Jung Award from the German Society of Clinical Neurophysiology and Neurology as a Neurologist. This was for his scientific work in the field of transcranial magnetic stimulation. Prof. Claus is an active member of the editorial board of the scientific Journal for Clinical Neurophysiology (Thieme Publisher, Stuttgart).
In 1986 he was Guest Research Fellow, Prof. J Kimura, Univ. Iowa, USA, for 6 weeks, and at the same year the General Medical Council, London, registered him as a Neurologist.
In 1987 he spent a year at the National Hospital Queen Square as a research fellow neurologist of the Royal Society, working with Professor P.K. Thomas and Professor Anita Harding amongst others. Since then he has retained his membership of the Queen Square Alumnus Association, and he is in regular contact with many physicians and colleagues from the United Kingdom. Prof. Claus was elected Corresponding Fellow of the American Academy of Neurology and of the Royal College of Physicians, London.
His areas of interest as a neurologist are Clinical neurology including stroke prevention, epilepsy, neurodegenerative disorders, movement disorders, polyneuropathies, and neuromuscular disorders.
Among all this Prof. Claus has a huge experience dealing with high techniques diagnostic equipments such as the colour coded duplex sonography; transcranial colour coded duplex and 24 hour blood pressure monitoring that use in Stroke prevention and Check-up and Headache work up beside the Muscle nerve investigation (neuromuscular disorders, muscle pain, entrapment neuropathies): 17-20 MHz colour coded ultrasound.
He is experienced in the use of Botulinum toxin for the treatment of dystonias, spasticity, and pain disorders.
As a neurologist, he also gives talks on various neurological topics:
Muscle pain, lumbar disc disorders, treatment of muscular strain with Botulinum toxin
Primary and secondary stroke prevention, diagnostic techniques and medical therapy
Headache – Migraine, differential diagnosis and treatment, pain treatment including Botulinum toxin in headache
Epilepsy, clinical manifestation and treatment
Peripheral nerve disorders (polyneuropathies) differential diagnosis and specific therapy
Movement disorders, clinical manifestation and treatment
Multiple sclerosis, diagnosis and therapy
In carpal tunnel syndrome (CTS), one of the nerves to the hand (the median nerve) becomes compressed as it passes through the wrist. There are different causes which can lead to CTS like occupational overstressing of the hands, injuries at the wrist with malposition of the carpal bones, arthritis, pregnancy, diabetes, overweight and others. Also a genetic predisposition is discussed. In many cases, no single cause can be identified. It may be that a combination of risk factors contributes to the development of the condition.
The typical symptoms are numbness or tingling in the thumb, index, middle and ring finger, later pricking and painful paraesthesias. Sometimes the whole arm up to the shoulder is affected. This happens during the night or after awaking in the morning; but also with certain hand positions like keyboard typing, holding a phone or reading a newspaper, cycling or motor biking. The symptoms are intensified by overloading the hands by repetitive manual work. At the beginning the discomfort can be reduced by “shaking” the hands. Later a persistent numbness may occur. Left untreated, carpal tunnel syndrome can lead to constant pain and to permanent nerve and muscle damage that could severely limit your ability to use your hands.
Your doctor will conduct a neurological examination. Tests with pressure on the median nerve at the wrist, produced by bending the wrist (Phalen`s maneuver) or tapping on the nerve (Tinel`s sign) can bring on the symptoms in many people. Important is to prove the feeling in your fingers and the strength of the muscles in your hand. Nerve conduction studies (an electrodiagnostic test) can pinpoint damage to the median nerve by measuring how fast electrical impulses move through it. Up to 10 percent of people with carpal tunnel syndrome, however, test is normal when this method is used. Other examinations like electromyogramm, SEPs (sensory evoked potentials), ultra sonic or MRI might be necessary to rule out other conditions like nerve root irritation or compression at the cervical spine.
Fortunately, for most people who develop carpal tunnel syndrome, proper treatment usually can relieve the tingling and numbness and restore wrist and hand function, especially if you catch the condition early.
Nonsurgical therapy is possible if you have mild to moderate symptoms and the neurological examinations do not show an extensive damage at the median nerve. Medication with anti-inflammatory drugs (NSAIDs) such as Ibuprofen may help relieve pain from carpal tunnel syndrome only in the short term.
The most effective conservative treatment is nocturnal splinting with a specially wrist splint. If you use it, avoid wearing it all day, since that can weaken your muscles in your wrists and hands. Wearing it all night, however, is recommended. This should be done at least for 3 month.
If the symptoms persist or the nerve conduction velocity becomes worse, surgery has to be considered. Two main types of surgery are used to relieve the pressure on the nerves inside the carpal tunnel: open carpal tunnel release and the newer endoscopic carpal tunnel release. Both are outpatient procedures performed under local anesthesia (the surgeon cuts the ligament along the middle of the palm and inner wrist). Most people make a full recovery, but in some cases (fewer than 5 percent) carpal tunnel syndrome recurs after surgery. This happens more commonly following the endoscopic procedure, which often doesn’t open up the tunnel as fully as open release.
Restrictions of the following neuropsychological or cognitive functions are typical features of dementia:
3. comprehension and speech faculty
4. the ability to write and calculate
(The most common form of dementia)
In the case of Alzheimer’s disease certain proteins accumulate inside or outside of the nerve cells of the brain. The thus affected cells deteriorate. This is why Alzheimer’s disease is called a neurodegenerative disease. The degenerated cells can no longer carry out their usual function and the distribution of neurotransmitters is reduced rapidly. The consequence of this is dementia.
Apart from these fairly common forms of dementia there is a large variety of illnesses accompanied by dementia.
In any case, the first signs of dementia should be examined closely at an early stage to gain a secured diagnosis and act accordingly.
(Second most common form of dementia)
Vascular dementia is caused by a vascular disease of the brain. Microangiopathies (damages to the small vessels) or macroangiopathies (damages to the large vessels) for example by arteriosclerosis may lead to reduced local blood flow in certain parts of the brain.
The thus affected nerve cells deteriorate and can no longer exercise their task of distributing neurotransmitters. The consequence is dementia.Since this process is locally restricted, it is important to examine the exact nature of dementia in order to start effective therapy at an early stage.
Epilepsy is an illness of the brain which expresses itself in fits or seizures or convulsions. The most well-known form of fit is the generalized tonic-clonic seizure or convulsions, which comes along with loss of consciousness, drop or convulsions. There are, however, other forms of seizures that are not so commonly known, which express themselves in the twitching of an arm or a leg or disorder of consciousness or absences.
The causes for epilepsy are manifold and can have their origin in brain damage or hereditary facts. However, due to the drug development of recent years there are very efficient possibilities to treat patients with epilepsy so effectively that the majority can lead an entirely normal life without any seizures at all. In severe cases neurosurgical interference may offer help.
In their anatomical course through the body and the limbs nerves might be damaged in various ways, the cause of damage most often being traumatic. Symptoms of nerve damage may be prickling, numbness and pain but also palsy or disorders of the bladder or the rectum. Lower back pain is one of the most common complaints today. Up to 80% of the US-Population will suffer from back pain at least ones in their lives. Back pain or lumbar pain is the largest cause of work-related absence in the United Kingdom.
Very often nerves are trapped at the spinal cord, the backbone or in their course to the limbs. The reason for this may be some injury, a slipped disk or the trapping of a nerve in a bony or connective tissue canal. A typical example is the carpal tunnel syndrome.
What to do? Prior to surgical decompression therapy, reliable neurological diagnostic methods should be applied to locate the damage exactly. Symptomatic therapy including physiotherapy and special back pain therapy might also be of help.
Are you suffering from headaches? You are not alone! Headache is a widespread disease. It occurs in different types and strengths and can impair the quality of living substantially. It is possible to do something against it. But before a therapy can be started it has to be found out what the reason is and a correct diagnosis has to be made.
There are many types of headaches. The most common are the primary headaches like migraine, tension headache or cluster headache or an analgetic headache. Your neurologist has to know how your headache feels like, where it starts; whether there are accompanying symptoms, how long it lasts and how often it occurs. Then he will do different medical examinations. After he knows the diagnosis he can give you an advice for the right treatment. Treatment is possible!
Migraine is one of the most frequent neurological diseases. Around the world about 10 percent of the adults are suffering of migraine, more women than men. The difference between the genders has most likely hormonal and genetic reasons. Typically it starts in adolescence. After the 50th year the frequency declines again.
It is a temporary dysfunction of the brain. During a migraine attack the blood vessels of the cerebral membrane are widened and infected. The nerve fibres around the vessels are irritated so heavily that they send pain signals.
The duration of a pain attack is between 4 to 72 hours. The frequency varies between once a year up to twice a week. The pain is moderate up to very violent. The characteristic is mostly pulsating and only on one side of the skull; but in some patients also on both sides. One side is more affected than the other. Very often people are having accompanying symptoms like nausea, vomiting, visual problems and are very sensitive against light, noise and odour. By physical exercises the pain increases.
There are different migraine triggers like stress, menstruation, alcohol, especially red wine, disturbances in the sleep-awake-cycle, irregular meals, weather changes, light stimulus, odour or pain in the neck. These triggers are very individual and vary even in one individual from time to time. But these triggers are not the causes of the disease they just stimulate it.
A typical migraine attack proceeds in 4 phases. During the lead time there exist no pains yet. There could be depressive reactions, irritability and agitation. Concentration might get reduced; people feel tired and have to yawn a lot. Oedema, constipation or a craving for sweet or greasy food may occur. The second phase might be an aura. Quite often there are visual problems with scintillating scotomas or double vision. But it also can be sensibility disturbances or movement and speech problems. An aura keeps from a few minutes up to one hour.
The third phase is the headache phase. The pulsating pain starts very often in the neck, spreads over the back of the head and settles behind the eye or at the temple. Most attacks are accompanied by vegetative symptoms. The whole body is affected. Some people are not able to continue their work. They have to lie down. They seek quietness and darkness, don`t want to hear or see anything or anybody. The duration of the headache might be up to 3 days if the attack is not interrupted by medication.
Hours or 1-2 days after a migraine attack (4th phase) people feel tired and exhausted, concentration is still reduced, mood might be swinging.
What can you do to ameliorate the migraine? Be active, you can do something.
- Learn good time management: plan your day schedule. Don`t forget enough time for brakes.
- Learn to say “No”.
- Don`t spread yourself too thin. Not everything has to be done right away.
- Think: “nobody is perfect!”
- Take life easier, enjoy it.
In severe cases it is useful to take special medication every day to reduce the number of attacks, the length of the single attack or to improve the effect of the acute medication. This medication has to be taken for at least three quarters of a year, sometimes longer. Your neurologist will find out which medication will be the best for you and will supervise you through the therapy.
There are different types of medication to treat the acute attack. In easier cases a painkiller like Panadol or Ibuprofen can be enough. A combination with a medication against nausea can be given. But mostly stronger medication is required. The triptans, a group of special migraine drugs, ameliorates the attack within 2 hours in most patients. The medication has to be taken as soon as possible. Then it helps the best. But be careful. You should not take any painkiller or any triptan more often than 10-12 times a month. Otherwise there is the danger to develop an analgetic headache, which means headache by the medication itself!
Multiple sclerosis is an auto-immune disease in which the auto-immune system of the body attacks the nerves and especially their myelin sheaths. The illness usually starts at a fairly young age and becomes chronic. Although this disease can as yet not be entirely cured, there is a variety of new drugs which are very effective.
Besides the necessity to apply the appropriate medication in order to alleviate symptoms like palsies, pains, vision disorders, blindness and other neurological symptoms, there are also physiotherapy and other therapeutic measures that can be helpful.
Most common symptoms of Myasthenia gravis are ocular symptoms (50%) of Drooping of the eyelids (ptosis), double vision (diplopia) and blurred vision. The disease can generalize including symptoms like weakness of facial and extremity muscles. Moreover patients could have difficulties in chewing, swallowing and speech. Respiratory weakness may produce acute respiratory failure.
The symptoms of Myasthenia gravis are negatively influenced by exercise, heat, illness, and stress. Normally they worsen in the evening and get better after resting.
Often myasthenia gravis is associated with other disease like rheumatoid arthritis , scleroderma and systemic lupus erythematosus. 65% of patients with myasthenia gravis have a hyperplasia of the thymus. 15% of patients with myasthenia gravis present a Thymoma.
Myasthenia gravis is a clinical diagnosis by specialized neurologist, supported by specific tests including Cholinesterase inhibitor tests, antibody detection test, EMG (Electromyography), Computed tomography (CT) and MRI of the chest, to detect thymoma or thymic hyperplasia.
The treatment of Myasthenia gravis is effective and most patients are able to live normal lives. Based on the clinical findings it could include certain drugs (Cholinesterase inhibitors, Immunosuppressant agents, Intravenous immune globulin (IVIG)), Plasmapheresis, Thymectomy, Physical therapy and Lifestyle changes.
Polyneuropathy means the affection of many nerves due to very different reasons and it can therefore develop many different symptoms. Most frequent are paraesthesia such as prickling, numbness, burning of the feet, but also palsies, disorders of speech and failure of cerebral nerves.
Similar to the variety of symptoms there is also a large variety of causes for this disease. The most frequent reason is a metabolic disorder such as diabetes mellitus. But also hereditary disposition, toxic inhibition or paraneoplastic development can cause polyneuropathy.
Accordingly, diagnostics and therapy of polyneuropathies are manifold and difficult. The therapeutic aim must be to prevent the deterioration of the nerves itself on the one hand and to treat the illnesses causing polyneuropathy on the other hand.
Should both turn out to be impossible, palliative methods may be used to ease the symptoms, especially pain, by applying special medication and physiotherapy.
Parkinson’s disease belongs to the group of movement disorders and expresses itself by trembling (tremor), rigidity (limb stiffness) and akinesia (diminishment of movements). Very often the changes in movement are very discreet and therefore an early diagnosis is often difficult. In the long run, however, Parkinson’s disease may result in severe handicaps and disabilities.
Aetiologically this is caused by the deterioration of specialized nerve cells which are responsible for the design, the development and the realization of movements.
However, there may be other symptoms such as a reduction of superior intellectual brain functions, psychic symptoms such as depression but also disorders of vegetative bodily functions.
Whereas in treating Parkinson’s disease the main focus will be on adequate medication, physiotherapy, dancing or other physical exercises are also useful therapeutic means.In severe cases neurosurgical intervention might be necessary which is known as deep-brain-stimulation.
A Stroke is a serious illness which can be fatal. It is caused by the occlusion of a blood vessel that supplies the brain. This will lead to the disturbance of relevant physical functions such as:
Acute palsies of arms, legs or parts of the face, numbness, prickling, speech disorders as well as other neurological defects.
Another cause for a stroke can be a cerebral haemorrhage which might occur due to the bursting of a cerebral vessel. Both forms of cerebral apoplexy need immediate treatment in a specialized hospital (stroke unit) where the trained doctors will try to dissolve the occlusion or stop the haemorrhage respectively.
Prior to all apopleptic events attention should be given to the above mentioned symptoms which are strong indicators of an arteriosclerotic process even though they might be only temporary. Such temporary attacks are known as TRANSIENT ISCHAEMIC ATTACKS. They must be taken seriously and must lead to the immediate consultation of a neurologist in order to avoid a more severe development of the symptoms.
After a stroke has taken place without early efficient clinical treatment and with following severe damages and disabilities, professional rehabilitation is necessary as early as possible to regain mental and physical abilities that might have been lost.
The causes of vertigo may be manifold. Most often vertigo is the consequence of damages to the internal ear, the equilibrium, the cerebellum or due to circulatory disturbances of the brain. But also heart diseases or low blood pressure may cause vertigo and dizziness. Even psychic disorders like panic attacks or anxiety can lead to vertigo.
It is therefore imperative that the exact nature of all vertigo complaints is determined in a multidisciplinary way involving especially the examination by a neurologist, an ear nose and throat specialist and a cardiologist.
After having spent one year of research in the USA, he continued his medical education at the University Hospitals Mannheim and Heidelberg and went on to work as Deputy Head at the Neurological Hospital in Erlangen.
From 1987 until 2010, Professor Koempf held the position as Director of the Neurological University Hospital of Luebeck, Germany where he worked as a Senior Consultant for Neurology, held lectures and taught students. In 2010 he was elected as General Secretary to the EFNS (European Federation of Neurological Societies) where he organizes large neurological conventions and further education for neurologists in Eastern Countries such as Russia, Belarus, Ukraine, Moldavia and others. Aim of these efforts is to standardize neurological diagnostics and treatment in Europe.
In 1998, Professor Koempf wrote an important book on the topic of “Clinical Neuro-Ophthalmology”, vertigo and visual problems which was published by the renowned Thieme Publishers. He also deals with all “Diseases of the Cranial Nerves” on which he also published a book in 2006.
Since finishing his Univerity career, Professor Koempf has been seeing patients in his private clinic in Luebeck and spends some months in Mallorca, Spain, in a Vertigo Center which he founded at Juaneda Hospital.
During his active time as Director of the Neurological Hospital at Luebeck University, Professor Koempf dealt with the whole range of neurological diseases including Parkinson’s disease, Epilepsy, Multiple Sclerosis, Cerebral circulatory disorders, stroke prophylaxis, disturbances of the memory, dementia, headaches, migraine, polyneuropathies, restles legs syndrome, back pain and diseases if the discs.
But above all, he concentrated on the numerous kinds of vertigo (of which there are about 50) as well as vision disorders or disturbances of the equilibrium. Vertigo itself is just a very general term which does not mean anything specific. One must differentiate between specific vertigo meaning everything is spinning and unspecific vertigo which may mean short loss of vision, dizziness or disturbed equilibrium.
The problem always is to find the underlying cause because very often the cause of very strong symptoms may be quite harmless whereas a slight symptomatology may indeed have a dangerous cause. In the latter case, a fast course of diagnostics is of the utmost importance in order to prevent for instance a stroke. The whole range vertigo lies between these two poles.
The most important issue when dealing with vertigo symptoms is the medical history and the correct analysis of the symptoms. At the beginning of this procedure there will be a thorough neurological examination with a focus on the eye movements. From time to time it will be necessary to carry out a psychiatric exploration as well because vertigo can be due to psychic problems. Following this will be neurophysiological investigations such as EEG, VEP, AEP or others and the DUPLEX ultrasound examination of the cranial arteries and a combined cooperation with an ENT doctor, an ophthalmologist, maybe an orthopedist and a qualified laboratory.
Despite his being in Dubai only recently, Professor Koempf realized that all services he needs for his highly specialized work are available in Dubai, predominantly offered by German colleagues such as ophthalmology, ENT, orthopedics, cardiology and laboratory. This makes diagnostics and treatment easier since they all follow the same high German standards and uncomplicated communication between them allows secured results. Professor Koempf is devoting some of his time at the moment to meeting and getting to know these colleagues in order to guarantee best results for his patients.
As main problems in this region, Professor Koempf notices so far the often faulty medicinal treatment of patients suffering from Parkinson’s disease or epilepsy, missing preventative measures for stroke and other diseases of the vessels as well as pain therapy regarding the numerous kinds of headaches or polyneuropathy caused by diabetes. Above all he is concerned about people suffering from dizziness and vertigo which is one of the most prevalent complaints presented in a neurological clinic and not to be underestimated regarding the possibly underlying serious causes.
Professor Koempf will continue to inform us about the topic of vertigo on this site.
