   Abstract : Identification of symptoms or biological abnormalities that predispose to suicide or identifies specific vulnerabilities, may one day improve allocation of resources or help tailor treatment to the patient. Paper I: We compared the predictive value of symptom-oriented questions against direct questions about suicidality in assessing risk for suicide attempts. READ MORE

5. 3. Analysis of regional atrophy on brain imaging compared with cognitive function in the elderly and in patients with dementia – cross-sectional and longitudinal evaluation

   Abstract : During aging, brain changes are not homogeneous throughout the entire brain, but are related to changes in the morphology of neurons, as well as to changes in the tissue density, and are specific to each region of the brain. Dementia is a broad category of brain disorders with a set of symptoms including memory, visual-spatial and language problems. READ MORE

6. 4. Hippocampal volumetry in mild cognitive impairment
