Task 1.

Two hours prior to admission to the emergency ward a 52 year- old man developed right arm, hand and leg weakness. At the time of examination, dysphasia and right face drooping were noted. Over the ensuing hour the patient became obtunded, areflexic on the right side, and completely unable to lift the right arm against gravity. The physical exam added no new information.

● What syndrome is revealed in the patient?

● What structures are involved?

● Where is the focus of the lesion?

Task 2.

A 65 year-old man complained of weakness in the right arm. For 3 months he had been dropping objects, and it was gradually getting worse. There were no sensory symptoms. On exam, the patient was mildly confused and speech was slow and slurred. The right nasolabial fold was flat. Muscle bulk was normal. No fasciculations were seen. Rapid passive movements of the right arm or leg met with resistance which would give way ("clasp-knife"). Strength was minimally diminished in the right intrinsic hand muscles, the wrist dorsiflexors, triceps, deltoids, iliopsoas, hamstrings and tibialis anterior. A right pronator drift was observed. Finger movements were slow on the right. The right leg circumducted while walking. Reflexes were hyperactive on the right. The right plantar response was extensor. Sensation to touch, pin, cool, vibration was normal. Two-point discrimination, point localization and graphesthesia were poorly done on the right in comparison with the left.

● List features of the clinical upper motoneuron and low motoneuron syndrome.

● What are possible sites of weakness in this case?

● Give a few etiological possibilities.

Task 2.

? 62 year old man complains of tremor of the right hand for six months. It began with an occasional tremor of the right thumb but has gradually spread to all fingers and is now continuous. He has also noticed that his handwriting has become smaller and more difficult to read. It is harder for him to use a toothbrush with the right hand and his wife must help him button the left shirt sleeve. She has observed that her husband occasionally drools and that his voice is softer. On examination, the patient is mentally normal but often responds slowly. The voice is soft and monotone. Facial expression and blink rate are diminished. He pushes off with his hands when arising from a chair and the gait is slowed with short steps and decreased arm swing on the right. There is a slow, resting tremor of the right hand which suppresses with maintenance of a posture. There is an occasional, asymptomatic tremor of the right foot. There is cogwheel rigidity in both upper extremities, the right more than left, with slowed repetitive movements of the right hand and foot.

-What is the diagnosis?

-Distinguish the following tremors: Parkinson's, Essential, Cerebellar.

-What is meant by "tone?" Distinguish flaccidity, spasticity, cogwheel rigidity, and paratonic ("lead-pipe") rigidity.

-What are the classical symptoms and signs of Parkinson's Disease?

Task 3.

You are asked to consult on a 35 year old woman hospitalized on the psychiatry service for evaluation of "muscle twitches." The patient is currently hospitalized for depression and anxiety. Further history reveals that the patient's work performance has declined over the past year associated with changes in personality and occasional poor judgment. The patient's family history reveals that her father died at age 50 in a nursing home of "Alzheimer's disease." The patient's paternal grandmother died in a mental institution of unclear cause. The patient's brother is described as being "restless." The patient's children are healthy. On examination, the patient is dysarthric and shows impaired memory and concentration on mental status testing. She has irregular "jerky movements," of the hands, feet, and trunk. These are rapid and non-stereotyped. The patient's saccades are slow but with full eye movements. There is a milkmaid's grip. The patient has an unusual gait disorder, placing the feet irregularly with a tendency to trip and demonstrate

"dancing like" movements.
