Our result provides evidence for larger similarity in intrinsic brain activity between healthy older persons and patients with or at-risk for AD than between older and younger ones, suggesting a significant  ...  Independently of applied methods and involved areas, healthy older persons' intrinsic brain activity was consistently more alike that of patients than that of younger controls.  ...  The authors are grateful to the participants of the study and the staff of the Department of Psychiatry and Neuroradiology for their help in recruitment and data collection.  ...

Sleep and Circadian Rhythm Disorders in Human Aging and Dementia [chapter]

M.V. Vitiello
2009 Encyclopedia of Neuroscience  
Both of these changes are indicative of impaired sleep maintenance and depth and contribute to the characterization of the sleep of older adults as lighter, or more fragile, than that of younger adults  ...  Aging is also associated with a tendency to both fall asleep and awaken earlier. That is, a tendency for older individuals to be larks rather than owls.  ...  See also: Aging of the Brain and Alzheimer's Disease; Alzheimer's Disease: An Overview; Alzheimer's Disease: Molecular Genetics; Alzheimer's Disease: Transgenic Mouse Models; Animal Models of Alzheimer's  ...

Conclusions: Relative to PD no-ICD, PD-ICD patients are characterized by a more severe involvement of frontal, meso-limbic and motor circuits.  ...  Furthermore, in PD-ICD, the lack of increased functional connectivity within the sensorimotor-network together with their cortical thinning in the same regions, suggest a greater disconnection among these  ...  Conclusions: The role of genomic SNPs still represented a challenge for the genetics of SAD, having an effects in increasing the risk for SAD, if any, much smaller than those of APOE.  ...
