The biomedical therapies and preventing psychological disorders:
Biomedical therapy:
o Prescribed medications or procedures that act directly on the person's physiology
o Change the brain chemistry with drugs
o Psychotherapy can be considered a biological treatment because changing the way we think
and behave in a brain-changing experience
Drug therapies:
Psychopharmacology
o The study of drug effects on mind and behavior
o Revolutionized the treatment of people with severe disorders
Drug therapy is greeted with wave of enthusiasm as many people apparently improve
Is the drug actually working or because they believe it is working they see positive results
Thanks to double- blind study where neither the researcher nor the participant know who is
getting the actual drug and the placebo show that the several drug types effectively treat
psychological disorders
Antipsychotic drugs:
Antipsychotic drugs:
o Drugs used to treat schizophrenia and other forms of severe thought disorder
Dampened responsiveness to irrelevant stimuli

effective in changing negative symptoms such as apathy and withdrawal
Similar to molecules of neurotransmitter dopamine to occupy its receptor sites and block its
activity
Overactive dopamine system contributes to schizophrenia
Side effects: sluggishness, tremors, twitches similar to Parkinson's disease
Long term use can produce tardive dyskinesia (involuntary movements of the facial muscles)
With proper social support, the right drugs and therapy people with schizophrenia can live mostly
a normal life
Antianxiety drugs:
Drugs used to control anxiety and agitation such as Xanax or Ativan
Depress central nervous system activity
Combined with psychological therapy to enhance exposure therapy's extinction of learned fears
and to help relieve the symptoms of PTSD and OCD

treatment

withdrawal symptoms
