Psychiatry . . .
What is Psychiatry?
Psychiatry is a branch of medicine which deals with the identification and treatment of mental illness. Clinical psychiatry is practiced by a licensed medical
professional (M.D.) who is board certified in psychiatry. A licensed psychiatrist:
- may enter private practice and offer various forms of psychotherapy and
medical treatments (i.e., psychotropic drugs, etc.) to individuals,
families, and groups.
- can furnish legally-recognized clinical and
diagnostic opinions and conduct diagnostic interviews regarding
the presence, scope, and treatment of behavioral disorders, mental
illness, and mental disease.
- can legally prescribe psychotropic drugs to
treat mentally ill patients and admit them to a mental or medical
hospital.
- is not usually trained to administer and interpret standardized psychological and neuropsychological tests.
What's the difference between a psychiatrist and a psychologist?
Psychologists and psychiatrists are equally qualified to give an opinion on an individual's psychiatric/mental status, treatment regimen, disability status, and back-to-work prognosis. The primary difference between them is not one of credentials but of function: The psychiatrist is licensed to treat mentally ill patients medically (i.e., prescribe psychotropic and other prescription drugs) and admit them to a mental health facility or hospital; the psychologist is licensed to treat mentally ill patients with psychotherapy and related therapeutic regimens, but may not in New York
and some other states, admit the patient to a hospital.
Neuropsychology . . .
What is Neuropsychology?
Neuropsychology is a highly specialized
discipline within the field of psychology. The science of neuropsychology focuses on cognition, i.e., the ability of the mind and brain to think, reason, remember, learn, comprehend, etc. Clinical neuropsychology is practiced by a licensed psychologist specializing in neuropsychology. This specialty field has developed a variety of clinically standardized tests and procedures
to evaluate the cognitive and functional effects of brain injury,
brain damage, and organic brain disease. A clinical neuropsychologist:
- may enter private practice and offer various forms of psychotherapy
and cognitive rehabilitation to individuals, families, or groups.
- can administer standardized psychological and neuropsychological
tests to patients in office and hospital settings, and interpret and report on their results.
- may furnish legally-recognized clinical and diagnostic opinions and conduct diagnostic interviews regarding the presence, scope, and treatment of cognitive/neuropsychological disorders, behavioral disorders, and mental illness.
What's the difference between Neuropsychology and Neurology?
Neurology is a field encompassing the science
and study of the human brain and nervous system and its diseases.
Clinical neurology is a specialty field of medicine; a
clinical neurologist is an M.D. who is board certified in
neurology. The function and practice of a clinical neurologist
differs substantially from that of a neuropsychologist. Since
there is great confusion between the two, it is important to carefully
note the differences:
The neurologist M.D. deals with the structural
and physiological consequences of brain injury and organic
brain disease, while the neuropsychologist Ph.D. investigates
the cognitive and behavioral impact of such conditions.
For example, an individual suffers serious brain damage in a car
accident. The neurologist will run tests and make determinations
as to the physical impact of injuries: Can the patient
ambulate, move limbs and muscles, and maintain hand/eye coordination?;
Is an EEG needed? How severe is soft tissue damage?; Is surgery
in order?; etc. The neuropsychologist, on the other hand, will
examine and test the patient's powers of cognition: Can
the patient think and reason clearly?; Is long and short-term
memory impaired?; Have reading, learning, and comprehension been
compromised?; etc.
It should further be noted that in disability
determinations and related procedures, the neurologist is not
"more important or qualified" in medical or legal terms
than the neuropsychologist. The neurologist M.D. is qualified
and licensed to make a clinical assessment regarding a patient's
physical disability status as a result of brain damage;
the neuropsychologist Ph.D. is qualified and licensed to make
a clinical assessment of the patient's cognitive disability
status. Both have important, but different, functions in examining
and treating individuals suffering from head injuries and brain
damage.
What cognitive areas are assessed in a neuropsychological evaluation?
Standardized neuropsychological tests used to assess cognitive functioning can detect
and quantify impairments in:
- short and long-term memory functioning in all sensory modalities
- verbal and non-verbal problem-solving and reasoning abilities
- attention span and orientation to time, place, and space
- language recognition and speech competence
- visual-motor coordination and sensory abilities
- the ability to plan, abstract, and synthesize information
