Parkinson’s Disease

 

For Prelims:About Parkinson’s Disease

 

Why in the news?      

            Researchers recently said that a higher-than-expected prevalence of gene mutations in Parkinson's disease patients indicates that genetic testing should be offered to them more broadly.

 

About Parkinson’s Disease:

  • It is a progressive neurological disorder that affects the nervous system and the parts of the body controlled by the nerves.
  • It is a condition in which a patient has limited or no control over his movements and body balance.
  • The risk of developing Parkinson’s disease naturally increases with age, and the average age at which it starts is 60 years old.
  • Many studies have suggested that men are more likely to be affected by Parkinson’s than women.

Cause of the disease:

  • It is caused by the degeneration of nerve cells in the part of the brain called the substantia nigra, which controls movement.
  • These nerve cells die or become impaired, losing the ability to produce an important chemical called dopamine.
  • Dopamine operates with other neurotransmitters to help coordinate the millions of nerve and muscle cells involved in the movement.
  • Lack of dopamine causes the slowed movements and tremors symptoms of Parkinson's disease.

Symptoms of the disease:

  • Parkinson's disease symptoms can be different for everyone.
  • Early symptoms may be mild and go unnoticed.
  • Symptoms often begin on one side of the body and usually remain worse on that side.

Parkinson's symptoms may include:

○Tremors (trembling in the hands, arms, legs, and jaw); rigidity (stiffness of the limbs); slowness of movement; and impaired balance and coordination.

○Patients may also experience other symptoms such as difficulty in swallowing, chewing, and speaking, urinary problems, constipation, skin problems, depression, emotional changes, and sleep disruption.

  • Diagnosis: Currently, no blood laboratory or radiological tests are available to diagnose Parkinson’s disease.
  • Treatment: There's no cure for this disease, but treatments can help significantly improve your symptoms.
