In Parkinson's disease, inadequate levels of dopamine lead to movement difficulties and cognitive symptoms in patients.
Dopamine is the neurotransmitter whose inadequate levels in the brain cause the slow or shuffling gait in Parkinson's disease. Loss of dopamine neurons in the substantia nigra leads to symptoms like tremors, slowed movement, and balance problems.
In addition to motor symptoms, patients with Parkinson's disease can experience cognitive symptoms and psychological issues as the disease progresses. The reduction in dopaminergic transmission contributes to the characteristic movement difficulties seen in this condition.
