For years, psychiatrists and psychologists have lacked physiological proof of the "disordered" mentalities they diagnosed. Brain imaging technologies changed all that by offering hard evidence of the differences between the brains of patients and of people without mental illness. Now, a recent study from German scientists confirms theories of mental dysfunction underlying depression, while the research also shows how depressed brain activity can be normalized following psychotherapy — minus any form of drug therapy.
For some time now, neuroscientists using brain imaging technologies have been able to examine the changes that occur in the brains of patients as a result of mental illness. Depression, in particular, marks the brain in a particular way.
“The human brain responds to depression,” Dr. Svenja Taubner, lead author and professor in the department of psychology at the University of Kassel, explained in a press release. “Patients typically show hyperactivity particularly in the amygdala, the striatum, and other limbic regions.”
Along with this characteristic hyperactivity, depression also produces generalized network dysfunction, as neuroscientists conceptualize it, in the cortico-limbic loops. Since depression affects the functioning of the brain, it only stands to reason that successful treatment would impact the brain as well. In other words, patterns of hyperactivity should normalize as a patient’s mood stabilizes.
However, this is where brain imaging studies fall short — some studies show increased hyperactivity in limbic and subcortical regions following psychotherapy treatment, while others show decreased hyperactivity. Taken together, the studies did not prove psychotherapy could normalize the brain of a patient. For the current study, then, the researchers wanted to confirm the positive effects of psychotherapy.
No Drugs
The experiment they designed worked like this: The researchers examined and scanned the brains of 18 patients with recurring depressive disorders and a control group of 17 healthy people. Then, after the patients underwent eight months of psychotherapy, all the participants were examined again.
For the depressed patients, the researchers selected four sentences to represent their personal dysfunction theme, so to speak, before psychotherapy began. One patient, for example, exemplified these four sentences: “You wish to be accepted by others;” “Therefore, you do a lot for them;” “That is often too close for them, so they retreat;” “Then you feel empty and lonesome.” These sentences served as stimuli during the MRI sessions — the researchers read these trigger sentences while peering into the patient's brain using the technology.
What did the researchers see? Before psychotherapy, the sentence stimuli triggered hyperactivity in the limbic system within each depressed patient's brain. Yet, following eight weeks of psychotherapy, the patients' brains had normalized and their limbic systems did not hyper-react to the stimuli.
Psychotherapy, the researchers explained, helps patients accept and gain insight into their dysfunctional relations, and as a result, patients do not become emotionally aroused when they are forced to confront their so-called “issues.” For anyone suffering depression, this study validates the benefits of drug-less psychotherapy. Going forward, the researchers expect to report a second follow-up study after 20 months of treatment.

The study also revealed that individuals who quit smoking, regardless of age, can achieve a life expectancy similar to non-smokers within approximately 10 years after quitting, and nearly half of this benefit can be noticed within just three years.
Researchers found that a combination of genetics and environmental factors reduces longevity in dementia patients. The same combination may shorten the lives of their siblings even without dementia.
The suicide rates increase substantially when air pollution rises, and the effect was particularly strong in the elderly, with older women 2.5 times more at risk than other groups.
While mental stress is commonly acknowledged in connection with grief, it is crucial to understand that grief can also present physical symptoms, including illnesses, fatigue, pain, and sleep disturbances.
The use of antidepressants, particularly fluoxetine, could affect the development of the prefrontal cortex of the infant's brain, potentially raising the risk of mental health disorders later in their life.
Researchers have developed smart earrings that could continuously monitor a person's earlobe temperature. The innovation known as Thermal Earring could also be potentially used to track signs of ovulation, stress, eating, and exercise.
The researchers made the interesting finding using a trial involving patients with a rare genetic condition called Alpha-1 antitrypsin deficiency (AATD).
People infected with the flu were more likely to need hospital care in the following year for common neurologic conditions than people who had the SARS-CoV2 infection.
Among women with a history of pregnancy complications, those who achieved or maintained high heart health after pregnancy were at a similar risk for heart disease as women without adverse pregnancy outcomes and good cardiovascular health, the study stated.
The study published in the journal BMJ indicated that individuals with hypermobile joints had a 30% higher chance of not fully recovering from COVID-19 and experiencing persistent fatigue associated with long COVID.
The studies showed that COVID antigens lingered in the blood up to 14 months after infection and more than two years in tissue samples of people who had the infection.
Those individuals who receive a COVID-19 vaccine during the first half of their menstrual cycle are more likely to experience cycle length changes than those receiving a vaccine in the latter half.
