Final answer:
Supportive therapies are utilized in the treatment of HD when symptoms do not impair function, with medication to control mood and movements, along with various types of therapy to maintain functional abilities. Aricept is used to slow Alzheimer's progression, with ongoing research into early detection and potential new therapies.
Step-by-step explanation:
When treatment for Huntington's Disease (HD) is required, but the symptoms are not severe enough to impair function, physicians may turn to supportive therapies. These therapies can include medication to manage symptoms such as depression, mood swings, and involuntary movements. Physical therapy, occupational therapy, and speech therapy may also be beneficial in improving functional abilities. Even with current therapies, HD remains a progressive and lethal condition, and much research is dedicated to finding more effective treatments. Areas of particular focus include neuroprotective strategies, symptomatic therapeutics, and potentially disease-modifying therapies.
While there is no cure for conditions like HD, Alzheimer's disease can be treated with drugs such as Aricept, which work by inhibiting the enzyme acetylcholinesterase to help slow down the progression of cognitive decline. However, these treatments cannot restore lost memories or cognitive functions. Early detection of Alzheimer's disease, potentially through a new blood test that identifies Aß molecules, may increase the chances of slowing the progression of the disease.
