The neurotrophic hypothesis of depression [1] proposes that major depressive disorder (MDD) is caused, at least partly, by impaired neurotrophic support.Neurotrophic factors (also known as neurotrophins) are a family of closely related proteins which regulate the survival, development, and function of neurons in both the central and peripheral nervous systems.
Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the ventral tegmental area and the substantia nigra, the latter of which contains neuromelanin ...

The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 1 ]
Serotonin syndrome, in which an excess of serotonin in the synapses causes a similar crisis of hypertension and mental confusion, could be confused with an adrenergic storm. Serotonin, being a tryptamine (non-catecholamine) involved in higher brain functions, can cause dangerous hypertension and tachycardia from its effects on the sympathetic ...
Humans, as well as a portion of the other animals that utilize l-DOPA, make it via biosynthesis from the amino acid l-tyrosine. l -DOPA is the precursor to the neurotransmitters dopamine , norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines .
These findings suggest that AMPT's effect on alertness and anxiety is catecholamine-specific and further supports that catecholamines are involved in the regulation of normal states of arousal and pathological anxiety symptoms. [22] Patients have reported hand, leg, and trunk tremors as well as tightening of the jaw post AMPT drug therapy.
It is speculated to have a role in depression, as some depressed patients have been reported to exhibit lower concentrations of metabolites of serotonin in their cerebrospinal fluid and brain tissue. [30] Norepinephrine is a member of the catecholamine family of neurotransmitters.
