Objective: Depression and cognitive deficits are amongst the main mental health problems in the elderly. Frequently both conditions happen together and cause serious consequences like reduction in the quality of life, functional deficits, increase in the use of health services, and increase in morbidity and mortality. Recognizing the main cognitive alterations caused by depression syndrome is very important to confirm the diagnosis, plan the treatment, and establish parameters about the prognostic of these patients. The goal of this article is to review the studies published over the last years about cognitive alterations in the elderly diagnosed with depression.
Method: In order to do so, relevant studies over the period of 1991 through 2005 were selected using Medline.
Discussion: These studies' results point out to cognitive deficits that go beyond memory deficits, and which are relevant both to the differential diagnosis between depression and dementia, as well as depression and normal aging, and to monitor more closely those patients who have increased risk of converting to dementia in the future.

The latest studies have demonstrated that aberrant expression of microRNA-146a is related to cognitive decline. The rs57095329 polymorphism occurring in the miR-146a promoter modulates its expression and causes downstream pathogenicity. A case-control study in a Chinese Han population was established to investigate the genetic association between the miR-146a rs57095329 polymorphism and postoperative cognitive dysfunction (POCD).

Down syndrome (DS) is a genetic intellectual disorder caused by trisomy of chromosome 21 (Hsa21) and presents with a variety of phenotypes. The correlation between the chromosomal abnormality and the resulting symptoms is unclear, partly due to the spectrum of impairments observed. However, it has been determined that trisomy 21 contributes to neurodegeneration and impaired neurodevelopment resulting from decreased neurotransmission, neurogenesis, and synaptic plasticity.

Alzheimer's disease (AD) is a neurodegenerative disorder clinically characterized by progressive decline of memory and cognitive functions, and it is the leading cause of dementia accounting for 60%-80% of dementia patients. A pathological hallmark of AD is the accumulation of aberrant protein/peptide aggregates such as extracellular amyloid plaques containing amyloid-beta peptides and intracellular neurofibrillary tangles composed of hyperphosphorylated tau. These aggregates result from the failure of the proteostasis network, which encompasses protein synthesis, folding, and degradation processes.

Background And Aim: To date, there is no treatment to prevent the development of temporal lobe epilepsy, the most common form of drug-resistant epilepsy. A recent study revealed the antiepileptic-like effect of the aqueous extract of . Given the potential of this extract, the antiepileptogenic- and learning and memory-facilitating-like effects of the aqueous extract of were assessed using the kainate-induced post- model.

Background: We have noted that some adolescents and young adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) report difficulty with arms-overhead activities, suggestive of brachial plexus dysfunction or thoracic outlet syndrome (TOS). In the TOS literature, diagnostic maneuvers focus on the provocation of upper limb symptoms (arm fatigue and heaviness, paresthesias, neck and upper back pain), but not on elicitation of systemic symptoms.
Objectives: To estimate the proportion of patients with fatiguing illness who experience local and systemic symptoms during a common maneuver used in evaluating TOS-the elevated arm stress test (EAST).
