A condition that affects a
person's
thinking, feeling,
mood, and behavior that can be caused from, perpetuated by, and affected by demonic spirits.
The lady banging her head against the
wall, waving her hands, and talking to herself out
loud to no one seems to have demental illness.
My friend who was traumatized, is suffering from demental illness that includes thoughts and feelings of
depression, grief, hopelessness and now suicide.
