This is the summary
Alcohol interferes with the brain's communication pathways, and can affect the way the brain looks and works. Also Alcohol myopia, in combination with distracting activity, can reliably reduce anxiety and depression in all drinkers by making it difficult to allocate attention to the thoughts that provoke these states. These theories are discussed in terms of their significance for the prevention and treatment of alcohol abuse. Drinking water and non-alcoholic cold liquids caused a marked fall in plasma adrenaline and a transient rise in noradrenaline concentration. In contrast, drinking alcohol resulted in a relative rise in adrenaline and a delayed increase in noradrenaline concentration. Blood glucose increased after alcohol, supporting a physiological effect of adrenaline on liver glycogenolysis. Plasma cortisol concentration was also significantly higher after drinking alcohol.
is proposed that the relative rise in adrenaline together with higher cortisol levels, repeated over a variable period in susceptible individuals, are implicated in the elevation of blood pressure associated with long term alcohol consumption. It concurs with observations in man and experimental animals of a slow pressor mechanism mediated by adrenaline.
