If you get down to the basic causes of both mental illness as it is called and neuropsychology or
even neurology, I find there is almost always a physical cause for both.
I think mental illness is an old term coined for the effects that a biological/physical problem creates.
Take many of the terms used for mental illness and you will see it has now been proven
through MRI, imaging technology, synapse and hormonal malfunctions make what we think of as
mental illnesses. And these malfunctions stem from the brain, so I would term it neuroscience.
A few examples:
Schizophrenia - genetic and caused from too much dopamine in the brain. Antipsychotics used to
treat are dopaminergic antagonists.
But, the outward effect is called a mental illness.
Unipolar and Bipolar depressions - multiple brain chemistry plays a role in these.
Seratonin. Too much or too little. When they alternate between too high and too low it's called manic or Bipolar depression. Too little and it's unipolar endogenous depression. Also norepinephrine and cortisol
are involved which comes from glands on kidneys that is triggered by brain signals.
Anxiety disorders and panic attacks - Adreneline and cortisol over production create the sensations experienced with these. Hyperventilation or overly anxious states can trigger the hormones, but,
so can the brain without the person doing anything consciously.
ASD - Genetic and neurological brain hard wiring from birth causing multiple issues.
Not all the same.
Psycopathy - Areas of the brain do not fire properly especially in the pre-frontal
areas where affective empathy occurs. Their brains also are shaped differently in the cortex
region esp.
Rule of thumb: Psychopaths are born, Sociopaths are made from life's experiences.
But, would any of these be called neurological? ASD, yes.
The other examples people call mental illness even if they are physically produced.
Neurological and bodily changes can result from reactive events such as PTSD, grief,
and reactive causes.
Most personality disorders are just that...personality that is Atypical.
Is that neurological or mental? Or just as it implies, personality?
Most all of what is termed mental illness has neurological basis.
Yet it isn't neurologists that treat them.
The question was asked what do neurologists do?
Their area is mostly confined to brain and nervous system disorders that
affect the body, such as Parkinson's, MS, palsy, Muscular dystrophy and Alzheimer's, brain
tumors, brain injuries.
And they make a lot of money.
