NPH is characterized by three primary symptoms. The first is difficulty walking, also known as gait disturbance. The individual may struggle to lift their feet off the ground when walking, and “tend to walk with their legs wide apart and their body bent forward,” says the Alzheimer Society.
The second main symptom is dementia, which includes forgetfulness, short-memory loss, apathy, struggles with planning and decision-making, and changes in personality or behavior. And the third symptom is a loss of bladder control, which the Alzheimer’s Association says “tends to appear somewhat later in the disease.”
