A 56-year-old patient with transient loss of vision in one eye followed by weakness and numbness in the opposite hand likely has what condition?

The scenario presented describes a patient experiencing transient loss of vision in one eye, followed by weakness and numbness in the opposite hand. This clinical picture is suggestive of a transient ischemic attack (TIA) or a stroke, but the specifics lean more towards a stroke due to the symptoms and the progression.

A stroke occurs when there is a sudden interruption of blood supply to the brain, leading to neurological deficits. The transient loss of vision may indicate that blood flow was temporarily reduced to the areas of the brain controlling visual processing, such as a potential occlusion in the posterior circulation. The subsequent weakness and numbness affecting the opposite hand suggests that additional neurological pathways were impacted, correlating with the side of the body opposite to where the brain injury occurred, a characteristic effect of central nervous system strokes.

While a transient ischemic attack also presents with similar symptoms, the key difference lies in the duration and permanency of symptoms. TIAs typically resolve within 24 hours without lasting effects, whereas this question hints at a potential more significant event, especially considering the progression of symptoms.

Lacunar infarcts refer to small, deep brain infarcts that can result in specific deficits but do not typically manifest with transient vision loss as an initiating symptom. Lastly, migraines
