> There have been a kazillion different proposed targets for depression based on many of the kazzillion findings of abherant brain function in depressed patients. Studies of which include:
>
> -Neurotransmitters (Serotin, Dopamine Etc)
> -Neuromodulators (Gaba, Glutamate)
> -Trace Amines (PEA, tryptamine, etc.)
> -Neuropeptides (Neuropeptide Y, ghrelin)
> -Opiate function (kappa, mu, delta, etc)
> -Nerve Growth Factors (NGF, FGF, BDNF, GDNF)
> -Signal Transduction (Protein Kinases)
> -Ion Chanels (Calcium, Sodium, Potassium)
> -Cellular Metabolism (ATP)
> -Regulation of Apoptosis (BCL-2, Bax)
> -Kinases (MAP kinases, stress induced kinases)
> -HPA axis (and genes that regulate it)
> -Immune function (TNF alpha)
> -Cellular Adhesion Molecules
> -Supporting Brain Cells (Glia)
> -Structural (ie. grey matter changes)
> -Cellular Morphology
> -Antioxidant Defense Systems
> -Genetics
> -Environment

> When you are depressed, there can be so much out of wack. What would make somebody conclude that they know the one (and only) possible problem (i.e. my dopamine receptors are not working properly)? Anhedonia is a core feature of depression. Depression is associated *many* *many* possible brain changes.
