What neurological deficit may be caused by a right hemisphere stroke?

A right hemisphere stroke is often associated with specific neurological deficits that can manifest in various ways due to the localization of brain functions. One of the hallmark symptoms is the neglect of the left side of the body, known as unilateral neglect or hemispatial neglect. This occurs because the right hemisphere of the brain is primarily responsible for spatial awareness and attention to the left side of space. When a stroke affects this area, the individual may be unaware of the left side of their body and the surrounding environment.

This neglect can lead to significant challenges in daily activities, as the person may not respond to stimuli on the left or may not even realize that their left limbs are in their own field of vision. Understanding this deficit is critical in stroke rehabilitation, as targeted interventions are needed to help the individual regain awareness and function.

In contrast, difficulty in speech production is typically associated with strokes affecting the left hemisphere, which is dominant for language in most right-handed individuals. Weakness in the right arm would also signify a left hemisphere stroke, as the brain controls contralateral motor function. Impaired visual recognition may not be as closely tied to a right hemisphere stroke specifically and can occur in various contexts and stroke locations. Thus, the neglect of the left side of the body
