Parkinsonism Clinical Features Explained
Parkinsonism is a clinical syndrome characterized by specific motor symptoms. Let's examine the features provided:
- Hypomimia: Often referred to as "masked facies," this is the reduced or diminished facial expression seen in Parkinsonism due to decreased muscle movement.
- Dysphonia: This involves impaired voice production, often presenting as a soft, breathy, or monotonous voice, which is a common symptom in Parkinsonism.
- Festination gait: Characterized by short, shuffling steps and increased speed, this abnormal gait pattern is a hallmark of Parkinsonism.
- Cogwheel rigidity: This is a type of muscle stiffness where resistance to passive movement intermittently catches or releases, described as a ratchet-like movement. It is a classic sign of Parkinsonism.
All the listed clinical features—hypomimia, dysphonia, festination gait, and cogwheel rigidity—are generally considered characteristic signs and symptoms associated with Parkinsonism.
Important Questions from Neuropathies
- Circuits between the basal ganglia and the motor cortex constitute the extra pyramidal system which controls muscle tone, body posture and the initiation of movement. Lesions of the extra pyramidal system present clinically with :
Consider the following statements regarding Transient Global Amnesia (TGA):
1. TGA mainly affects middle aged persons who present with abrupt, discrete loss of anterograde memory lasting for few hours.
2. During the episode, the patients are unable to record new memories resulting in repetitive questioning.
3. Consciousness is impaired during the episode and the patient is unable to perform even simple motor functions.
4. After 4-6 hours, memory function and behaviour return to normal but the patient has complete and persistent amnesia for the duration of the episode.
