rechterhemisfereschade

Rechterhemisfereschade refers to damage of the right hemisphere of the brain. The right hemisphere is responsible for spatial perception, attention to the left side of space, visual and auditory processing, and aspects of language such as metaphoric meaning and prosody. Damage to this area can arise from trauma, stroke, infection, tumor, or neurodegenerative disease.

The clinical presentation of rechterhemisfereschade varies with lesion size and location. Common symptoms include left hemianopia or left neglect (failure to attend to the left side of the body or environment), impaired lateralized mental imagery, difficulties in navigating familiar spaces, and in some cases, impaired ability to describe or understand non‑literal language. Patients may also show deficits in emotion recognition, especially negative emotions, and reduced awareness of left‑sided bodily sensations (anosognosia). In severe cases, alexia or dysgraphia may occur when the lesion involves adjacent language‑associated cortical areas.

Diagnosis is performed by a combination of neurological examination, neuropsychological tests, and neuroimaging. Computerised tomography (CT) or magnetic resonance imaging (MRI) is used to identify the lesion. Neuropsychological assessments such as line bisection tests, star cancellation, and error monitoring examine spatial and attentional deficits.

Management is multidisciplinary. For stroke‑related damage, acute reperfusion therapy or thrombectomy may limit tissue loss. Rehabilitation focuses on perceptual and attentional retraining, use of visual cues, and training of bilateral sensory integration. Occupational therapy may assist with spatial‑skill relearning. When neglect is present, prism adaptation therapy can improve left‑side awareness. Pharmacologic interventions are typically adjunctive and aim to support comorbid conditions such as depression.

Prognosis depends on lesion extent and the effectiveness of early intervention. Many patients experience partial recovery of attention and spatial processing over months to years, though residual deficits often persist. Research on neuroplasticity, cognitive training, and emerging neuromodulation techniques continues to investigate improved outcomes for individuals with rechterhemisfereschade.
