I reviewed this 58-year-old, right-handed retired architect gentleman in my clinic. He gives a history of insidious onset of a resting tremor in his right hand approximately one year ago, which has progressively worsened. Over the past six months, he has also noticed increasing stiffness in his right arm and leg, leading to difficulty with fine motor tasks such as writing and buttoning shirts. His wife reports that his gait has become slower and he occasionally shuffles his feet. He denies any recent head trauma, significant changes in vision or hearing, or numbness or tingling sensations.
He explicitly states no history of seizures, severe headaches, or visual disturbances. There is no mention of problems with bladder or bowel control, or significant weight loss.
His wife, who accompanied him to the appointment, corroborates the history of a progressive right-sided tremor and stiffness. She also noted that he has become more quiet and withdrawn recently, and occasionally experiences difficulty initiating conversation.
His father suffered from essential tremor, and his mother had type two diabetes. There is no other significant family history of neurological conditions. He has one sister who is in good health.
Mr. David Smith lives with his wife in a detached house and remains independent with activities of daily living, although some tasks are becoming challenging. He occasionally consumes alcohol, approximately two units per week. He quit smoking twenty years ago and denies any illicit drug use. He is currently not driving due to concerns about his reaction time and motor control.
Examination:
On general inspection, Mr. Smith is a well-nourished gentleman who appears to be his stated age. His vital signs are stable: blood pressure one hundred and thirty over eighty-five millimetres of mercury, heart rate seventy-two beats per minute, respiratory rate sixteen breaths per minute, and temperature thirty-six point eight degrees Celsius. He has a mild hypomimic facial expression.
Neurological examination reveals an alert and oriented individual with intact higher cognitive functions. Cranial nerves two through twelve are grossly intact, with full extraocular movements and no facial asymmetry. Motor examination demonstrates mild rigidity in the right upper and lower extremities, with a four hertz resting tremor in the right hand. Power is five out of five bilaterally in all muscle groups. Sensory examination to light touch, pinprick, and vibration is intact throughout. Deep tendon reflexes are two plus and symmetrical bilaterally. Coordination is mildly impaired on the right side with finger-to-nose testing. Gait is slow with reduced arm swing on the right, and he exhibits a mild shuffling pattern with some difficulty with turning.
Previous Investigations:
A recent full blood count, urea and electrolytes, and liver function tests performed on 1 November 2024 were all within normal limits. A brain MRI performed three months prior to this consultation showed no acute intracranial pathology or significant structural abnormalities.
Clinical Opinion and Recommendation:
Mr. Smith presents with a classic clinical picture of early-onset Parkinson's Disease, characterised by unilateral resting tremor, bradykinesia, and rigidity. The insidious onset and progressive nature of his symptoms, coupled with the absence of atypical features, strongly support this diagnosis. We have discussed the diagnosis in detail with Mr. Smith and his wife, including the chronic and progressive nature of the condition.
We plan to initiate treatment with Carbidopa/Levodopa, starting at a low dose of twenty five/one hundred milligrams three times a day, and titrate upwards as tolerated to achieve optimal symptom control. We will also refer him for comprehensive physical therapy to improve gait and balance, and occupational therapy to address his difficulties with daily tasks. Lifestyle modifications, including regular exercise and a balanced diet, were encouraged.
Mr. Smith will be scheduled for a follow-up appointment in three months, on 1 February 2025, to assess his response to medication, monitor for any side effects, and re-evaluate his overall clinical status. Further investigations, such as a DAT scan, may be considered if there is diagnostic uncertainty in the future. We will also monitor for any non-motor symptoms such as mood changes or sleep disturbances at subsequent visits.
