Let's first clear up a few confusing statements in your question:
1. Nobody can become crazy because of too much studying. Rather, one can become mentally tired or exhausted because of too much studying; but not crazy. Possible reason(s) for âbecoming crazy or madâ are either organic in nature (brain damage) or unknown (idiopathic). Madness due to brain damage is called psycho-organic syndrome. Madness due to idiopathic reasons is called psychosis. Psychoses are probably genetically conditioned. Psychoses include schizophrenia, bipolar disorder, paranoia, paranoid conditions, etc.
2. A shot or injection that will prevent someone from becoming crazy does not exist! There are medications that exist for treating, but not for preventing, madness. For example, anti-psychotics, antidepressants, and anxiolitics are medicines used for treating âmadnessâ and âcrazinessâ.
Cerebral atrophy is not a specific brain disease but only a pathologic term for organic damage of the brain. During this condition, the brain (especially the cortex) decreases its dimensions (atrophy). Brain atrophy causes disorders in all 3 main brain functions: sensory perception (senses), motor movement, and cognitive perception(emotions, memory, thinking, intelligence). Cerebral atrophy can be seen on a CT-scan.
