The Art of Aging: Limitless Potential of the Brain

This is an excellent video talking about how seniors can help keep their brains young.

How can we live a fuller and healthier lifestyle as we get older? Perhaps keeping our body and brain engaged can help. That seems to be the case in Japan where the number of centegenarians is greater than 20,000.

THE ART OF AGING:THE LIMITLESS POTENTIAL OF THE BRAIN introduces a number of these “super-seniors” who lead healthy lives at nearly 100-years-old and, through them,searches for the “keys” to living a healthy and vital life regardless of age.

Dementia and Alzheimer’s Disease: LORETA findings

Thanks to Jay Gunkelman who made a very informative post on January 27 on this forum entitled Dementia and Alzheimer’s Disease. There he described the EEG patterns that we should expect and detect when evaluating for AD or other dementias.

I’d like to just throw out there a few other findings that were discovered in a few exploratory investigations while working on some studies with our colleague Alicia Townsend, at the time at Univ. of North Texas. Lexicor funded these projects and now the arrangements are such that I can’t disclose more than was published in the abstracts from our talks at ISNR and AAPB. I did at least want to point to these very preliminary findings because theoretically they are in concert with your explanations.

First, we explored 10 participants between the ages of 65 and 85 were recruited at the University of North Texas Health Science Center. Each was diagnosed by the Alzheimer’s Disease Assessment Scale and a medical interview. The aim of the study was to identify current source density markers in AD. EEG recording of the eyes closed condition of an AD group was compared to an age-sex matched control group using within-subject multiple t-test procedures. sLORETA difference maps in nine frequency bands were investigated. Interestingly the results showed that there was a significant increase in current source density in the delta and theta bands in the Brodmann Area (BA) 39 of the right temporal lobe and BA 31, the cingulate gyrus respectively. Additionally there were decreases in alpha in the BA 21 of the right temporal lobe and right inferior parietal lobule (Sherlin, Townsend & Hall, 2006).

Dementia & Alzheimer’s Disease (AD)

I often get questions about Alzheimer’s Disease (AD) and the EEG.

Whenever a client presents with the question of dementia, all other forms of
dementia need to be ruled out before you are left with the diagnosis of AD.
There are many EEG signatures of various forms of dementia, all of which are
helpful in evaluating a client’s presentation of dementia.

Done by experts in EEG in dementia, the EEG and qEEG may be of substantial
additive value in the differential diagnosis puzzle that all cases of
dementia represent clinically.

One EEG pattern seen in dementia is the presence of periodic triphasic
slowing in the EEG, which is actually diagnostic of subacute sclerosing
panencephalitis (SSPE). SSPE is a “spongiform encephalopathy” where the
brain becomes like “Swiss cheese”, with holes scattered throughout. This
periodic triphasic finding is differentiated from MULTIFOCAL triphasics
which are diagnostic of Crutzfeld-Jacob Syndrome (CJD), which in lay terms
is a form of mad cow disease in humans.
