- Electroconvulsive therapy in the treatment of depression in anorexia nervosaby K van der Lelie on October 14, 2021
CONCLUSION: From the literature, clinical recommendations cannot be made binding. No randomized controlled trials have been published on this subject. However, we saw in our case study and in the literature found that clearing the depressive symptoms through electroconvulsive therapy led to an improvement in food and fluid intake. ECT has no effect on their deranged thought pattern.
- Relating neurosteroid modulation of inhibitory neurotransmission to behaviourby Delia Belelli on October 13, 2021
Studies in the 1980s revealed endogenous metabolites of progesterone and deoxycorticosterone to be potent, efficacious, positive allosteric modulators (PAMs) of the GABA(A) receptor (GABA(A) R). The discovery that such steroids are locally synthesised in the central nervous system (CNS) promoted the thesis that neural inhibition in the CNS may be "fine-tuned" by these neurosteroids to influence behaviour. In preclinical studies, these neurosteroids exhibited anxiolytic, anticonvulsant, analgesic...
- Blood-Brain Barrier Dysfunction in the Pathogenesis of Major Depressive Disorderby Shusheng Wu on October 12, 2021
Major depression represents a complex and prevalent psychological disease that is characterized by persistent depressed mood, impaired cognitive function and complicated pathophysiological and neuroendocrine alterations. Despite the multifactorial etiology of depression, one of the most recent factors to be identified as playing a critical role in the development of depression is blood-brain barrier (BBB) disruption. The occurrence of BBB integrity disruption contributes to the disturbance of...
