Riddoch syndrome
Riddoch syndrome
Riddoch syndrome (/ˈrɪdɒk/), also known as Riddoch's phenomenon or Riddoch's syndrome, is a rare neurological disorder characterized by the ability to perceive motion in an otherwise visually impaired field. The syndrome is named after George Riddoch, a British neurologist who first described the condition in 1917.
Etymology
The term "Riddoch syndrome" is derived from the name of George Riddoch, who first described the condition in a series of patients during World War I. Riddoch was a British neurologist and military doctor who made significant contributions to the understanding of war neuroses and the effects of gunshot wounds on the nervous system.
Symptoms
The primary symptom of Riddoch syndrome is the ability to perceive motion in an otherwise visually impaired field. This means that while a person with this condition may not be able to see stationary objects in certain parts of their visual field, they can still detect moving objects in these same areas. Other symptoms may include visual field loss, visual agnosia, and hemianopsia.
Causes
Riddoch syndrome is typically caused by damage to the occipital lobe of the brain, which is responsible for processing visual information. This damage can occur as a result of stroke, brain injury, or other neurological conditions.
Diagnosis
Diagnosis of Riddoch syndrome is typically made through a combination of clinical examination and neuroimaging studies, such as MRI or CT scan. The diagnosis is often confirmed when a patient demonstrates the ability to perceive motion in an otherwise visually impaired field.
Treatment
There is currently no cure for Riddoch syndrome. Treatment is typically focused on managing symptoms and may include visual rehabilitation therapy and the use of assistive devices to help improve visual function.
