Parkinson’s Disease Symptoms 

       Parkinson’s Disease (PD) is a neurodegenerative disorder that leads to a decline in the brain's dopamine levels. Dopamine is a crucial neurotransmitter responsible for regulating muscle movement. The reduction of dopamine results in abnormal motor functions.

Key motor symptoms include : 

• Tremor 
• Rigidity 
• Bradykinesia 
• Hypokinesia
• Postural instability 
• Freezing of gait

Non-motor symptoms include : 

• Constipation
• REM sleep behavior disorder
• Psychiatric symptoms such as depression, hallucinations, and obsessive-compulsive behaviors
• Cognitive decline or dementia

These symptoms may vary in severity and progression from person to person, and both motor and non-motor symptoms significantly affect the quality of life in individuals with Parkinson's disease.
