True or False: Pseudoparkinsonism can be effectively treated by discontinuing the causative agent.

Pseudoparkinsonism is a drug-induced condition that mimics the symptoms of Parkinson's disease and is often caused by the use of certain antipsychotic medications, particularly those that block dopamine receptors. The primary approach to treating pseudoparkinsonism involves identifying and discontinuing the offending agent, as removal of the drug can lead to a significant reduction or complete resolution of symptoms.

When the causative agent is withdrawn, the normal balance of neurotransmitters, particularly dopamine, can often be restored, thereby alleviating the parkinsonian symptoms. This treatment is typically effective, especially if the discontinuation occurs early after the onset of symptoms.

In instances where symptoms persist despite discontinuation, other treatments might be considered, such as the use of anticholinergic medications or beta blockers, but these are not the first line of intervention. Thus, the straightforward discontinuation of the causative agent is not only a common strategy but often an effective one in managing pseudoparkinsonism.
