Parkinson's disease is a chronic nervous system disorder affecting the movement. A person with Parkinson's disease faces difficulty in walking, balancing or coordinating, shows tremors or slow movements. Depression is common in chronic diseases. It is likely for a person with Parkinson's disease to suffer from depression due to their disabilities.
The neurotransmitters such as dopamine, serotonin, norepinephrine are known to induce positive emotions, evoking a "feel good" emotional state in a person. Also, Dopamine plays a crucial role in sending messages to the part of the brain responsible for regulating movement and coordination. Research suggests that the level of dopamine decreases in the person with Parkinson's disease due to the decline in the nerve cells that produces dopamine.
The major symptoms or conditions associated with Parkinson's disease includes rigid muscles, slowed down movements (bradykinesia), tremors, postural deficits, and speech problems.
Symptoms of Parkinson's disease:
- Slow movements or Movement deficits, these are the sign of parkinsonism related deficits, the person may show inconsistency in his movements, he might be walking perfectly at one moment and suddenly his movements will tend to slow down. This is associated with the decrease in nerve cells, which delays the neurotransmission of a signal, thus affecting the movements.
- It includes rigid muscles,
- tremoring while walking which can lead to falling.
- Stooped posture which causes imbalance.
- Problems with regulation of autonomic nervous system, involves problems related to blood pressure and digestion.
- Orthostatic hypotension, this refers to sudden drop in blood pressure.
- Urinary incontinence
- Dizziness
- Depression
- Attentional deficits
