Depression: Overview

319
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Atherosclerosis III: Management

19
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Antidepressant Drugs: MAOIs and Other Agents

304
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Depressive Disorders: MDD and Dysthymia

197
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Long-term Depression01:05

Long-term Depression

31.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Area of Science:

  • Gerontology
  • Nutritional Psychiatry
  • Epidemiology

Background:

  • Major depression significantly affects individuals aged 75 and over.
  • Depressive symptoms in the elderly are often overlooked or misdiagnosed as normal aging.
  • The Mediterranean diet's anti-inflammatory properties are hypothesized to counteract depression.

Approach:

  • A systematic review was conducted to evaluate the relationship between Mediterranean diet adherence and depressive symptoms in individuals over 65.
  • Nine studies were included from an initial pool of 317 identified manuscripts.

Key Points:

  • Adherence to the Mediterranean diet principles in older adults may offer protective benefits against depressive symptoms.
  • The review suggests a potential link between the Mediterranean diet and reduced occurrence or severity of depression in the elderly.
  • Further research is warranted to explore specific dietary components and their impact on geriatric mental health.

Conclusions:

  • The Mediterranean diet shows potential for the prevention and management of depression in the elderly population.
  • Findings support the investigation into the specific mechanisms through which the Mediterranean diet influences mental well-being in older patients.
