What causes frontal gait disorder?
Causes of frontal gait disorder The causes of FGD remain unclear. Cardiovascular risk factors, such as high blood pressure and high cholesterol, have been linked to vascular changes in the white matter of the brain and subsequent changes to walking.
Does hydrocephalus cause apraxia?
Normal pressure hydrocephalus (NPH) is a syndrome where there is a loss of higher function, a gait apraxia (p. 62) and urinary incontinence. This is associated with an enlargement of the lateral ventricles, but not the cerebral sulci, without obstruction.
How does NPH affect gait?
Specific features of the gait disturbance in normal pressure hydrocephalus were a broad based gait pattern with outward rotated feet and a diminished height of the steps. After treatment in both diseases, the speed increased, due to an enlarged stride length, now presenting a lower variability.
What is gait apraxia?
Apraxia of gait is a unique disorder of locomotion characterized by inability in lifting the feet from the floor despite alternating stepping action (frozen gait), and disequilibrium. Responsible site of lesions are in the frontal lobe and/or the basal ganglia.
What part of the brain is affected by apraxia?
Apraxia is caused by a defect in the brain pathways that contain memory of learned patterns of movement. The lesion may be the result of certain metabolic, neurological or other disorders that involve the brain, particularly the frontal lobe (inferior parietal lobule) of the left hemisphere of the brain.
What happens if NPH is left untreated?
The symptoms of NPH usually get worse over time if the condition is left untreated. Patients with untreated, advanced NPH may experience seizures, which can get progressively worse. Dementia and/or bladder control problems usually appear after gait disturbances as the condition progresses.
Does NPH make you tired?
Some people with NPH experience a rolling gait, often when tired or stressed. If you experience this all the time, go to your GP, as your shunt may need adjusting.
What is Visual apraxia?
Ocular motor apraxia (OMA) is the absence of, or a defect in, the control of voluntary, purposeful eye movement. Children with this condition have difficulty moving their eyes in a desired direction.
