- What biological markers have been found that might indicate the presence of Alzheimer's disease in a human being?Is Genetics a Factor in Parkinson's Disease?Alzheimer's disease is a progressive neurological degenerative disorder that affects almost 50 million people worldwide. The cause of Alzheimer's disease is still not well understood. It is thought to be a combination of genetics, lifestyle, and environmental causes. It is also difficult to diagnose Alzheimer's disease during the initial stages of the disease as symptoms can be mistaken for normal aging. Currently, there is no cure for the disease. Medication can help manage the symptoms but degeneration of brain tissue cannot be stopped or reversed. One medication used to manage the symptoms of Alzheimer's disease is a cholinesterase inhibitor. The medication helps to improve brain functioning and memory. What is the function of cholinesterase in the synapse? How does a cholinesterase inhibitor work in a synapse? Explain the function of cholinesterase inhibitor in increasing brain functioning and memory
- Research demonstrates substantial cognitive declines by older adults in laboratory tasks. However, older adults often do not show deficits when performing tasks during their everyday lives. (1) If laboratory performance by older adults is so different in terms of neurology as well as cognitive and emotional processing, how do they cope so well in everyday life? (2) How do differences between normal and pathological aging translate into differences in everyday functioning?Define the term denervation atrophy?Could you please mention/explain some limitations and extensions (three each) associated with the following claim and research question. Claim: Gene therapy can reverse ageing. Research question: How does the injection of BDNF in the brain through gene therapy help treat Alzheimer's disease in people over the age of 65? please asap
