Huntington’s is a progressive disease that affects a person’s motor abilities. Huntington’s is a genetic condition that begins with trouble in movement. The onset of dementia affects memory as a person is unable to learn new things and loses their sense of judgment. As the disease progresses further, a person’s intellect declines. Huntington’s disease can also affect people’s mental health. Therapies and medications directed towards symptoms can help. Normal Pressure Hydrocephalus (NPH) is a rare neurological disease that creates trouble in movement and leads to dementia. Due to enlarged ventricles – which are the areas cerebrospinal fluid collects in the brain – this can lead to a triad of difficulty walking with a particular pattern of gait, difficulty controlling urine, and memory changes. Due to its similarity to other neurological disorders, many tests are required to diagnose it, and it often goes undiagnosed. Creutzfeldt-Jakob disease is a rare yet fatal abnormality of the brain that can result in death within a year. Initial symptoms include weak memory, loss of body control, behavioral changes, and blurred vision, which escalate with time and lead to complete loss of memory and blindness. CJD is caused by abnormal forms of proteins in the brain, called “prions.” HIV associated dementia (AIDS dementia) is caused by an infection that spreads across the brain and escalates with the symptoms of dementia. The membranes of the brain swell, causing abnormality in brain functions.
