Final answer:
Haloperidol can have serious side effects on the nervous system, particularly those related to motor control, caused by its interference with dopamine activity in the basal nuclei. Severe side effects include insomnia, depression, prostate enlargement, liver dysfunction, and cardiac impairments.
Step-by-step explanation:
The side or adverse effects of haloperidol, an antipsychotic medication, can impact various regions of the nervous system, particularly those involved in motor control. These side effects may manifest as movement disorders which resemble those seen in the extrapyramidal system, hinting that the basal nuclei are a likely source of these effects. Haloperidol interferes with dopamine activity, which plays a crucial role in the function of the basal nuclei.
Some severe and possibly irreversible side effects of haloperidol include insomnia, depression, and prostate enlargement. Additionally, movement disorders akin to those observed in extrapyramidal system disorders can occur, indicating a significant impact on the nervous system's motor pathways. It is also noted that this medication might be associated with synthetic hormones side effects such as liver dysfunctions, difficulty in urinating, testicular atrophy, and impaired cardiac function.
