Parkinson’s Disease

Neurological Disorders

Parkinson’s disease (PD) involves the malfunction and death of vital nerve cells in the brain. Some of these dying nerve cells produce a chemical, which sends messages to the part of the brain that controls movement. The exact causes behind the progressive loss of nerve cells are still unknown.


PD is a chronic and progressive neurological condition characterised by slowness of movement, stiffness, shaking and impaired balance. Along with these symptoms, people might experience speech problems (softened voice, slurred speech), swallowing problems, bowel and bladder problems, difficulties at night (discomfort in bed, cramps, disturbed sleep pattern) and tiredness during the day. Skin can become greasy and people might experience excessive sweating.


Constipation, bladder and sexual problems are common. People often experience depression, anxiety and memory problems. The progression of PD varies among different individuals. Symptoms continue and worsen over a period of years.


Only about 10-15% of PD cases have been linked to a genetic cause, whereas most cases of PD are called idiopathic or sporadic, meaning the cause is unknown.

1 Consultation
Initial consultation with a specialist physician.
2 Assessment
Appointment with a neuropsychologist in the Neuropsychiatric Laboratory for computerized, detailed assessments of cognitive deficits and other neuropsychiatric issues associated with Parkinson's.
3 Testing
Blood tests and imaging scans, outsourced to the highest quality and convenient centres in London.
4 Follow-up
When all results are available, a 2nd consultation with the doctor, where clinical diagnosis & follow-up strategy are discussed and explained.


At Dementech Neurosciences London clinic we are offering end-to-end services for all the different levels of care that a Parkinson’s patient requires. Risk assessments, prevention strategies and tools are used, as it is far more efficient to prevent a disease from developing rather than try to treat it once it has progressed.


However, in cases where a diagnosis of a disease has been established, our multidisciplinary team will do everything humanly possible to treat symptoms and prevent them from progressing further, hence improving the quality, the emotional health and well-being of each individual.

There are many medications and advanced treatments (including surgery) available to treat the symptoms of Parkinson’s Disease (PD), although none yet that actually reverse the effects of the disease. Moreover, the effectiveness of the main drug treatment can wear off over time and its long-term use can cause some people to develop involuntary twisting movements of the arms, legs or face called dyskinesia.


At Dementech Neurosciences, we offer a multidisciplinary approach to treat all the variety of symptoms of PD. We have in-house speech and language therapist, occupational therapist, dietitian, psychologist and psychiatrist to manage effectively Parkinson’s Disease symptoms and complications. We use state-of-the-art technology such as the PKG to monitor and effectively treat symptoms and complications of PD. Cognitive dysfunction is often an early feature of PD occurring even at the early stage of the disease.


At Dementech Neurosciences we use cutting-edge technology CANTAB to assess the severity of cognitive deficits in people with PD. This enables us to provide an early diagnosis of cognitive impairment and effectively manage it. We also provide genetic screening and counselling for the known genes associated to the familial forms of Parkinson’s Disease. Moreover, we offer the opportunity to participate in clinical trials testing novel pharmacological intervention, before they become available to the public, aiming to delay the progression of the disease.
