Study Shows How Impaired Brain Impacts Cognitive Function In Parkinson’s Patients

New Delhi: Researchers from the Indian Institute of Technology (IIT) Bombay have in a new study unravelled how disrupted brain activity impacts cognitive functions in Parkinson’s patients.

The study focussed on altered reward processing in Parkinson’s patients to decode why Parkinson’s patients lack motivation and have impaired decision-making. Parkinson’s disease is a neurodegenerative disorder mainly causing shaky limbs, muscle stiffness, and slow movements. However, some Parkinson’s patients also manifest symptoms such as a lack of motivation or disability in experiencing pleasure, attributed to a lack of dopamine hormone.

Commonly known as the ‘feel-good’ hormone, dopamine is generally produced when performing a pleasurable task or receiving a reward.
