Final answer:
Late-stage Huntington's Disease can cause severe complications including rigid muscles, balance and posture problems, speech changes, and psychological symptoms that may progress to dementia. Hepatic encephalopathy is a potential secondary complication due to liver failure, adding to the neurological decline.
Step-by-step explanation:
Complications in Late Huntington's Disease (HD)
Huntington's disease (HD) is a progressive brain disorder that causes uncontrolled movements, emotional problems, and loss of cognition. Late-stage HD often results in severe complications, which may include rigid muscles, balance and posture problems, as well as speech changes. These physical symptoms can lead to difficulties in performing daily activities and an increased risk of falls and injuries. Moreover, psychological symptoms such as cognitive decline are prominent, manifesting as disruptive memory loss, confusion regarding time or place, and challenges with planning and executing tasks. The progression of cognitive symptoms in late-stage HD may evolve into dementia, causing poor judgment and personality changes, which further complicates care and can lead to a need for full-time assistance.
In addition to the neurological complications, patients with HD can experience other health issues. Specifically, they may develop secondary conditions such as hepatic encephalopathy, which is a neuropsychiatric abnormality associated with liver failure. This condition can compound the neurological decline seen in HD. Understanding these complications is critical to providing comprehensive care and support for individuals living with HD.
