1. The author delineates the emergence of an important concept in the Neurochemistry of mental illness, that of a Cholinergic Factor in Mania. This concept which evolved steadily over a period of 22 years from 1950-1972, the author believes has given us our first significant insight into the etiology and treatment of the Manic state. 2. In addition, the author examines the Adrenergic-Cholinergic hypothesis of Mania and Depression and the Brain Cholinergic-Adrenergic Balance hypothesis for Mania and Schizophrenia. 3. Also described in this article are some successful preliminary attempts by others, to treat Mania with Phosphatidyl Choline and the author will present, for the first time, data relating to success with the use of Phosphatidyl Choline in bringing about permanent remission of mania in 10 treatment subjects since 1983. 4. In conclusion the author proposes a Cholinergic Insufficiency Hypothesis as a primary factor in the causation of Mania and comments on a presumptive role in the modulation and balance of Adrenergic Dominance by Presynaptic Receptors positioned on the Nerve Terminals of Adrenergic Neurons.

Bipolar disorder (BD) is a central nervous system condition that is typified by fluctuations in mood, oscillating between depressive and manic, and/or hypomanic episodes. The objective of this study was to test the hypothesis that strength training may act as a potent protector against behavioral and neurochemical changes induced by BD. A strength training protocol was performed with adult male Wistar rats, and seven days following the conclusion of training, a single ouabain injection was administered.

Electroconvulsive therapy (ECT) effectively treats severe psychiatric disorders such as depression, mania, catatonia, and schizophrenia. Although its exact mechanism remains unclear, ECT is thought to induce neurochemical and neuroendocrine changes. Positron emission tomography (PET) and single-photon emission computed tomography (SPECT) have provided vital insights into ECT's neurobiological effects.

Abnormal connectivity in the brain has been linked to the pathophysiology of severe mental illnesses, including bipolar disorder and schizophrenia. The current study aimed to investigate large-scale functional networks and global network metrics in clinical high-risk for bipolardisorder (CHR-BD, n = 25), clinical high-risk for psychosis (CHR-P, n = 30), and healthy controls (HCs, n = 19). Help-seeking youth at CHR-BD and CHR-P were recruited from the early intervention program at Dokuz Eylul University, Izmir, Turkey.

Obesity activates both innate and adaptive immune responses in adipose tissue. Adipose tissue macrophages are functional antigen-presenting cells that promote the proliferation of interferon-gamma (IFN-γ)-producing cluster of differentiation (CD)4+ T cells in adipose tissue of obese subjects. The increased formation of neopterin and degradation of tryptophan may result in decreased T-cell responsiveness and lead to immunodeficiency.
