Hemispatial neglect
Hemispatial Neglect[edit | edit source]
Introduction[edit | edit source]
Hemispatial Neglect is a neuropsychological condition characterized by a deficit in attention to and awareness of one side of the field of vision. This condition arises following damage to one hemisphere of the brain, leading to an inability to process and perceive stimuli on one side of the body or environment, which is not due to a lack of sensation.
Causes and Pathophysiology[edit | edit source]
Hemispatial neglect typically occurs due to brain damage, most commonly from a stroke. It affects the brain's attention networks, leading to a decreased awareness of space on one side of the body or environment.
Symptoms[edit | edit source]
Symptoms of hemispatial neglect may include:
- Failure to acknowledge objects or stimuli on one side of the body.
- Difficulty navigating or bumping into objects on the affected side.
- In severe cases, complete neglect of one side of the body or space.
Types of Neglect[edit | edit source]
Hemispatial neglect is most often contralateral to the damaged hemisphere (opposite side). However, ipsilesional neglect (on the same side as the lesion) has also been reported.
Diagnosis[edit | edit source]
Diagnosis involves clinical observation, neuropsychological assessments, and brain imaging techniques like MRI or CT scans to identify the damaged brain areas.
Treatment and Rehabilitation[edit | edit source]
Treatment strategies include:
- Physical and occupational therapy to improve awareness of the neglected space.
- Cognitive rehabilitation and exercises.
- Use of visual cues and prompts.
- In some cases, medication may be prescribed to improve attention.
Prognosis[edit | edit source]
The prognosis for hemispatial neglect varies, with some patients experiencing significant improvement while others may have persistent symptoms.
Impact on Quality of Life[edit | edit source]
This condition can significantly impact the quality of life, affecting daily activities, mobility, and independence.
Research and Advances[edit | edit source]
Ongoing research is focused on understanding the underlying mechanisms of hemispatial neglect and developing more effective treatment approaches.
