Some More Nonsense From My Brain

I was thinking about this as I dropped off to sleep last night, and hoped I’d remember it…

It probably won’t make much sense, but I feel I need to get it written down before I forget, and I can always revisit it later.

I’ve written before about how I feel that there’s a connection between mental states and blood flow in the brain. So last night, I was visualising a cross section of one blood vessel, and looking at how it acted in different circumstances, and it’s kind of crystallized, for the moment, my thoughts on the subject.

Psychosis seems to be the result, in those susceptible, of fluctuations in the tone of the blood vessels. Some things seem to stabilize this; smoking, medications etc.

Mania, insomnia and restlessness seem to be the result of dilation of the blood vessels. Things which cause dilation seem to tip the balance of mood towards mania – be that due to antidepressant use, warm environment etc. These states are treated using drugs which to an extent cause the vessels to narrow.

Depression, sleepiness, hallucinations seem to be the result of constriction of the blood vessels. These states are treated using drugs which to an extent cause the vessels to dilate.

Perhaps stability on medication and it’s delayed onset of action could be explained by it’s helping to maintain a standard tone in the blood vessels, thus avoiding the fluctuations which could lead to psychosis. Smoking cigarettes probably has a similar effect.

People suffering bipolar disorder are perhaps more sensitive to things which can cause these fluctuations in blood vessel tone, and swing from mania when they are dilated to depression when they are constricted.

I’m also thinking that people who are treated with both an antipsychotic and an antidepressant are probably more prone to relapse with a mood disorder as it would take less to destabilize the level of tone with two drugs having quite different effects (although together the “pulling in different directions” may result in a reduction in fluctuations). It wouldn’t take much of an environmental influence to push them toward mania or depression via an increase or decrease in blood vessel tone.

So, to summarise:

Unstable blood vessel tone = psychosis

Stable dilated blood vessel tone = mania

Stable constricted blood vessel tone = depression

Unstable blood vessel tone with tendency towards dilation = psychosis with mania

Unstable blood vessel tone with tendency towards constriction = psychosis with depression

Unstable blood vessel tone with extreme fluctuations = schizoaffective disorder

Blood vessel tone with extreme but stable changes in tone = bipolar disorder

 

I need to think a bit more about this. Could be delusional nonsense, haha, but I’m sure I’m onto something here.
