Hyperprolactinemia-induced acute ischemic stroke.

Area of Science:

• Neurology
• Endocrinology
• Cardiovascular Medicine

Background:

• Strokes are a leading cause of death, with ischemic strokes being the most common type.
• Platelet activation is crucial in thrombus formation, traditionally linked to factors like thromboxane A2 and thrombin.
• Hormonal influences on platelet activation, such as by prolactin, are an emerging area of research.

Observation:

• A 25-year-old male with a history of pituitary microadenoma and hyperprolactinemia presented with an acute ischemic stroke.
• The patient's stroke occurred in the context of non-compliance with prescribed medication.

Findings:

• This case represents the first documented instance of acute ischemic stroke in a patient with known hyperprolactinemia who experienced a stroke due to medication non-compliance.
• The findings suggest a potential association between hyperprolactinemia and increased stroke risk, particularly when hormonal regulation is compromised.

Implications:

• This case emphasizes the importance of considering hormonal imbalances, like hyperprolactinemia, in the etiology of ischemic stroke, even in young patients.
• It highlights the critical role of medication adherence in managing conditions associated with hormonal dysregulation and preventing cerebrovascular events.
• Further research is warranted to elucidate the precise mechanisms by which prolactin influences platelet activation and contributes to stroke risk.
