Tests and Diagnosis for Parkinson's Disease

  • Parkinson Disease
    Parkinson’s disease is a progressive neurological disorder caused by malfunction and death of nerve cells (neurons) in the brain. Because of the death of nerve cells, people with Parkinson’s don’t have enough of the chemical Dopamine. This causes their movements to slow down. Symptoms get worse over time. An estimated 7 to 10 million people worldwide are living with Parkinson’s Disease. These numbers are projected to escalate sharply as more people live longer.

Diagnosing Parkinson’s

There is no specific test to identify Parkinson’s and it is difficult to diagnose especially in the early stages. The doctor will take note of your medical and neurological history and ask you to perform certain movements and tasks, which is part of the neurological exam. Physical examination is a key criterion for diagnosis. The four main movement related symptoms characteristic of Parkinson’s are often the main diagnostic criteria on physical examination. These are:

1.    Tremors: are uncontrollable movement like shaking or back and forth movements of hands and legs. Can affect jaws and head in severe condition. Occurs only during rest.

2.    Postural Instability: Difficulty balancing in sitting or standing position. Increased risk of falling.

3.    Bradykinesia: is slowness of movement and speed. This occurs in reduction of involuntary movements like swinging of the arms while walking or blinking of the eyelids. It also reduces reaction times, or delayed initiation or freezing of a physical movement. This slowness is seen in doing simple tasks like buttoning shirt, brushing teeth, cooking. Parkinson’s patients may often appear clumsy.

4.    Muscular Rigidity: Stiffness of muscles in arms, legs, trunk and neck causing discomfort and resistance in moving. Can also cause pain, cramps and balance issues. You will have problems in moving arms, carrying out daily tasks, turning, breathing due to chest muscle stiffness and frequent respiratory infections. When the facial muscles get stiff, it leads to a mask-like appearance of the face or medically known as Parkinson’s mask or hypomimia. Facial masking brings about difficulty in chewing, swallowing and speaking. Showing expressions like smiling or frowning become reduced over time leading to a blank stare, drooling, jaw tightness etc.

Parkinson’s disease must be differentiated from Lewy body dementia as there is common movement related symptoms. But Lewy body dementia is associated with fluctuations or changes in concentration and awareness and recurrent visual hallucinations or delusions.

  • Parkinson's Disease - The Shaking Palsy
    Dopamine is a Brain Chemical that helps to control muscle movement. In Parkinson's Disease the brain cells that make dopamine slowly die. The resultant lack of dopamine in body leads to physical symptoms such as slowness of movement, unusual stiffness in body, tremors and loss of balance. Depression, anxiety, constipation, speech-swallowing problems are some of the many other affections of Parkinson's Disease.          
  • Rigorous exercise may slow Parkinson’s Disease Progression
    Dr. Pettarusp Wadia, Consultant Neurologist and Movement Disorder Specialist, Jaslok Hospital and Research Centre, Mumbai, speaks to Dr Shital Raval about the latest treatments to manage Parkinson’s Disease.  Is Parkinson's a genetic condition? In about 5% of the adult population and 25% of the young-onset Parkinson's disease population, a single gene can be identified. However research is on to identify if certain genes make a person more susceptible to develop…

    Mrs Balasubramaniam has been looking after her husband, 83, who has Parkinson’s Disease, for more than a decade. She shares symptoms, treatments and caregiving tips.   When was your husband diagnosed with Parkinson’s Disease? My husband was diagnosed with Parkinson’s Disease about 10 to 12 years back, but he probably had symptoms much before that were not very noticeable, such as mild abnormality of gait or sticking out his tongue occasionally. What were the early…

    Parkinson’s Disease
    Parkinson’s disease is a progressive neurodegenerative disorder caused by deterioration of nerve cells (neurons) in the part of the brain called the substantia nigra. The death or damage to the nerves and the central nervous system causes deficiency of one of the important chemical neurotransmitter or messengers called dopamine. The lack of or decrease in the dopamine levels hinders the brain from sending signals to other cells within the brain and muscles. Movements tend to slow down or…
  • Patients with Parkinson's Disease often suffer from undiagnosed depression
    Depression is known to be a common symptom of Parkinson's disease, but remains untreated for many patients, according to a new study by Northwestern Medicine investigators in collaboration with the National Parkinson's Foundation (NPF). http://www.medicalnewstoday.com/releases/281162.php
