One meta analysis on first episode depression observed distinct patterns of grey matter reductions in medication free, and combined populations; medication free depression was associated with reductions in the right dorsolateral prefrontal cortex, right amygdala, and right inferior temporal gyrus; analysis on a combination of medication free ...
The kindling hypothesis of depression posits that each period of depression in someone with major depressive disorder (MDD) causes neurological changes that predispose the person to future episodes. While the first episode of depression is often triggered by major life events, future episodes are less likely to be tied to circumstantial factors ...
“Depression is a lot of different things with a lot of different causes, biological changes and treatments,” said Dr. Richard Keefe, professor emeritus of psychiatry and behavioral sciences at ...
It studies how economic behavior can shape our understanding of the brain, and how neuroscientific discoveries can guide models of economics. [ 1 ] It combines research from neuroscience , experimental and behavioral economics , and cognitive and social psychology.
Depression is a significant mental illness with physiological and psychological consequences, including sluggishness, diminished interest and pleasure, and disturbances in sleep and appetite. [1] It is predicted that by the year 2030, depression will be the number one cause of disability in the United States and other high-income countries. [2]
In contrast to major depression, dementia is a progressive neurodegenerative syndrome involving a pervasive impairment of higher cortical functions resulting from widespread brain pathology. [ 7 ] A significant overlap in cognitive and neuropsychological dysfunction in dementia and pseudodementia patients increases the difficulty in diagnosis.
In physiology and medicine, depression [1] refers to a lowering, in particular a reduction in a specific biological variable or the functions of an organ. It is the opposite of elevation. For example, it is possible to refer to "depressed thyroid function" or to a depression of blood flow in a particular area. Further examples:
One reason depression is thought to be a pathology is that it causes so much psychic pain and distress. However, physical pain is also very distressful, yet it has an evolved function: to inform the organism that it is being damaged, to motivate it to withdraw from the source of damage, and to learn to avoid such damage-causing circumstances in the future.
