Parkinson's Disease

Parkinson's disease is a progressive neurological condition that impacts movement. It is triggered when the brain fails to produce sufficient quantities of dopamine, a neurotransmitter. Parkinson's disease is most common in men, and it typically begins around sixty years old. The symptoms of Parkinson's disease have a slow, gradual onset, and they usually start on one side of the body at first; both sides of the body display symptoms in the later stages. Patients may have tremors in the jaw or face, and tremors are also common in the hands, arms, and legs. The limbs and torso may feel stiff, and movements could be slower than normal. Poor balance and coordination might be present, and patients could have difficulty with walking, speaking, chewing, or swallowing. Depression and sleep difficulties are frequently reported. This condition is diagnosed with a neurological examination and a medical history. Medications are used to manage symptoms, and a surgical procedure known as deep brain stimulation may be considered for severe cases.
