A condition causing loss of tactile sensation on one side of the body due to vascular occlusion is known as?

The condition characterized by a loss of tactile sensation on one side of the body due to vascular occlusion is called hemianesthesia. This term specifically refers to a reduction or absence of sensation on one side, typically as a result of neurological impairment often seen in conditions such as stroke where blood flow to specific areas of the brain is compromised.

In the context of vascular occlusion, the affected area of the brain might be responsible for sensory processing, leading to diminished tactile perception on the opposite side of the body. This occurs because sensory pathways cross over in the central nervous system: thus, an issue on one side of the brain can result in sensory loss on the opposite side of the body.

Other terms like hemianopia, hemiparesis, and hemiplegia, while related to neurological conditions, refer to different deficits. Hemianopia relates to visual field loss, hemiparesis refers to weakness on one side of the body, and hemiplegia denotes complete paralysis on one side. Therefore, hemianesthesia is the precise term for the condition described, highlighting the specific sensory deficit resulting from vascular issues.
