Otetaanpa väliin tällainen mielenterveysaiheinen kirjoitus, liittyen aikamme kansantautiin. Etenkin näin marraskuun kurimuksen jälkeen, tämä aihe tulee jotenkin ajankohtaisena useammille.
Mielenkiintoista infoa on siis tullut, liittyen tilaan jossa henkilö kärsii niin masennuksesta, kuin ahdistuksestakin:
What Happens in the Brain of Someone Who's Both Anxious and Depressed
Normaalisti masennus heikentää ja kutistaa aivojen osia, mutta ahdistus estää sitä tekemästä niin. Jopa suurentaa aivoja ja sen osia, sekä luo jopa uusia yhteyksiä.
those with depression alone also have lower brain volumes, especially in the hippocampus. According to the study’s authors, this becomes even more relevant later in life because a smaller hippocampus is a risk factor for Alzheimer’s disease and may accelerate the development of dementia. The second finding revealed that when both anxiety and depression occur together, no shrinkage appeared to the hippocampus, and the amygdala—the part of the brain linked to emotions—increased in size.
What does this combined impact on the brain mean? The research team surmised that the pairing of anxiety and depression indicates that anxiety lowers the effects of depression on brain volume size by 3 percent. They concluded that the overactivity of anxiety causes the brain to make more connections and thus becomes larger. This can be problematic, according to the researchers, because the presence of anxiety along with depression and the enlargement can mask the shrinking effects of depression.
The findings that the brain gets bigger if a patient is both anxious and depressed also implies that the actual effect of depression on brain shrinkage has been underestimated because of the opposite masking effect in the amygdala. The investigators emphasized the need for future studies that examine anxiety comorbidity as a means to better understand the independent role of each disorder in brain structure.
Onkohan siis ahdistus jokin aivojen tapa suojata itseään/kompensoida, kun ne ovat ylikuormittuneet masennuksessa?
