Mental illnesses ???????????????

list as many different illnesses possible and give the symtoms / effects of each one please ??

also which is the most serious / dangerous mental illness of all

I would say physcosis is the most dangerous, the symptons, starting with manic depression, agression, leading on to voices in your head, or strong feelings to do harm to someone.
This can be managed by drugs but it will leave you in a sedated state. Best to be sectioned in cases like this for the indivduals safety and others.
My step father has it, it's not cool
I would also like to add this is not the individuals fault, it is a sickness and something they cannot prevent
