Simultaneously, a locus segregating with a minority of early-onset familial AD kindreds was mapped to this chromosome, in the same region as the APP gene. Subsequently, several missense mutations within the APP gene that resulted in amino acid substitutions in APP were identified in these familial AD kindreds. Such mutations appear to alter the previously described proteolytic processing of APP, generating amyloidogenic forms of Ab.
Research to date suggests higher blood levels of vitamin D may help prevent AD and recent animal studies indicate high-dose vitamin D supplementation may help treat the disease by reducing the abnormal proteins in the brain that are associated with the disease.
AD is the most common form of dementia. Currently, there is no cure for AD. There are two main changes that take place in the brain when an individual develops AD: Plaques, which are clusters of protein that build up between the nerve cells in the brain.
These stop cells from signaling to each other. Tangles, which are dead or dying nerve cells. These stop nutrients from moving through the cells, causing them to die. Some of the main symptoms are: Memory loss that affects daily life Having trouble planning or solving problems Not being able to complete everyday tasks Having trouble reading or judging distances Having poor judgment when making decisions Withdrawing from work, hobbies and social activities Getting confused about the time or location Changes in mood or personality, such as becoming easily upset, suspicious or anxious These are different than the normal changes that happen as some individuals age, such as occasionally forgetting names or losing things from time to time.
Such forgetting by young people reminds us that the forgetting that worsens as we age is seldom dementia. AD is very common; more than five million Americans are living with this disease, and one in nine people over the age of 65 have AD. Inthere were approximately While there are many factors that increase the chances of developing AD, scientists are still not sure what causes some people to get it.
Additionally, over time, brain cells death causes the brain to shrink, which affects brain function. AD is the result of many different factors, not just one single cause. Age is the main factor that increases your chances of developing AD.
You have an immediate family history of someone having AD. If your parent or sibling has AD, then you are more likely to develop AD. You have genes that are involved with the development of AD.
There are a few genes that scientists have identified which can have an influence on AD. You have had a serious head injury, especially repeated injuries. You have other health conditions, such as high blood pressure, heart disease, diabetes, high cholesterol or if you have had a stroke.
You are of African or Hispanic descent. Researchers have found that there is a link between vitamin D and brain function. This has lead researchers to study if vitamin D status may affect risk of developing AD. Some of the receptors in the brain are receptors for vitamin D, which means that vitamin D is acting in some way in the brain and influencing the way an individual thinks, learns and acts.
However, these researchers are still exploring whether taking vitamin D supplements can help prevent memory loss and dementia. Two recent journal articles reviewed all of the studies involving vitamin D and AD; both showed that vitamin D levels are lower in people with AD than those without AD.
For instance, some researchers theorize that if a person has memory loss or is developing dementia, they could be staying indoors more and making less vitamin D from sun exposure.Scientists may have inched closer to an effective method to prevent the onset of Alzheimer’s disease, the tragic neurological condition that causes loss of memory and other cognitive functions, generally in older people.

In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons.
The opposite of LTP is long-term depression, which produces a long-lasting decrease in synaptic strength..
