💊 Pseudoparkinsonism Induced by Chlorpromazine
✅ Answer: (c) Tremors, shuffling gait, and mask-like face
📖 What is Chlorpromazine?
Chlorpromazine is a first-generation (typical) antipsychotic medication used to treat schizophrenia, mania, severe nausea, and psychotic disorders.
👉 It blocks dopamine (D₂) receptors, which can lead to movement disorders called Extrapyramidal Symptoms (EPS).
📖 What is Pseudoparkinsonism?
Pseudo = False or resembling
Parkinsonism = Symptoms similar to Parkinson’s disease
👉 Pseudoparkinsonism is a drug-induced extrapyramidal side effect caused by dopamine blockade.
Common features include:
- Resting tremors
- Shuffling gait
- Mask-like facial expression
- Muscle rigidity
- Bradykinesia (slow movements)
❌ Why Other Options Are Wrong?
(a) Restlessness and showing tics
❌ Indicates Akathisia, characterized by an inability to remain still.
(b) Continuous muscle twitching
❌ More suggestive of muscle fasciculations or other neuromuscular disorders, not pseudoparkinsonism.
(d) Extremity spasm and difficulty walking
❌ Suggests Acute dystonia, which causes painful muscle spasms and abnormal postures.
📝 Common Extrapyramidal Symptoms (EPS)
| EPS Type | Main Features |
|---|---|
| Pseudoparkinsonism | Tremor, rigidity, shuffling gait, mask-like face |
| Akathisia | Restlessness, inability to sit still |
| Acute Dystonia | Painful muscle spasms, torticollis, oculogyric crisis |
| Tardive Dyskinesia | Lip smacking, tongue protrusion, involuntary facial movements |
Parkinson’s Disease = TRAP
Tremor
Rigidity
Akinesia (slow movement)
Postural instability
Drug-induced Parkinsonism looks the same → Tremor + Shuffling gait + Mask-like face.
📌 Exam Tip: Typical antipsychotics such as chlorpromazine and haloperidol commonly cause extrapyramidal symptoms (EPS). Pseudoparkinsonism usually develops within days to weeks after starting therapy.
