The term young onset dementia is becoming more widely used to avoid the potential confusion between early onset dementia and early stage dementia. This term is now used as presenile dementia which is a historical term of people diagnosed with dementia from a younger age of 51 years old. This is caused by an atypical arteriosclerosis of the brain.
Most cases of early-onset Alzheimer's share the same traits as the "late-onset" form and are not caused by known genetic mutations. Little is understood about how it starts. Nonfamilial early-onset AD can develop in people who are in their 30s or 40s, but this is extremely rare, [3] and mostly people in their 50s or early 60s are affected.
Neuroplasticity, also known as neural plasticity or just plasticity, is the ability of neural networks in the brain to change through growth and reorganization. Neuroplasticity refers to the brain's ability to reorganize and rewire its neural connections, enabling it to adapt and function in ways that differ from its prior state.
The Nun Study of Aging and Alzheimer's Disease is a continuing longitudinal study, begun in 1986, to examine the onset of Alzheimer's disease. [1] [2] David Snowdon, an Epidemiologist and the founding Nun Study investigator, started the Nun Study at the University of Minnesota, later transferring the study to the University of Kentucky in 1990.

The onset of the deficits has been between the ages of 40 and 90 years and finally there must be an absence of other diseases capable of producing a dementia syndrome. Possible Alzheimer's disease : There is a dementia syndrome with an atypical onset, presentation or progression; and without a known etiology; but no co-morbid diseases capable ...
The critical period, defined as the beginning years of brain development, is essential to intellectual development, as the brain optimizes the overproduction of synapses present at birth. [2] During the critical period, the neuronal pathways are refined based on which synapses are active and receiving transmission. It is a "use it or lose it ...
A new machine learning model can predict the eventual occurrence of dementia, according to a new study. Its authors say the model is greater than 80% accurate and can predict disease up to nine ...
By their usual definitions, childhood dementias always cause global neurocognitive decline. In some childhood dementia conditions the child's early development is indistinguishable from their healthy peers, then slows or plateaus before declining. In other childhood dementia disorders, early development may be slower than typical before declining.
