Neuropsychological Assessment - What is a Neuropsychologist?
The goal of a neuropsychologist is to assess, understand, study and treat behaviors directly related to brain functioning. People who have sustained brain trauma or tbi from car accidents or who have early dementia are good candidates for neuropsychological tests done by the neuropsychologists. Most neuropsychologists work in research settings such as laboratories, universities and research institutions.
Others practice in clinical settings, involved in the treatment and assessment of patients with neuropsychological problems.
Some work in industrial or forensic settings as consultants where neuropsychological problems exist. A few work in pharmaceutical fields where the drugs being tested might have CNS effects.
Even though the title “neuropsychologist” is a relatively new one, its roots can be traced to ancient Egypt at least. People in ancient times were looking at the functions of the brain.
For many centuries, the brain was felt to be completely useless-not the center of bodily function as it now is. Only Imhotep, an Egyptian priest and physician seemed to understand the role of the brain in the body.
In the 18th through 20th centuries, increasing knowledge was learned by various anatomists, psychologist and physicists about the structure and function of the brain. Slowly a picture of the brain has been uncovered, including what parts of the brain are responsible for different functions in the body
In the latter half of the 20th century, the discipline of neuropsychology was born. Research was directed at how the brain affected both the body and personality. Then mental disorders and cognitive impairments were since identified.
Different treatment plans and tests have been developed over the years based on the dysfunctions identified by neuropsychological testing.
The field of neuropsychology is still evolving with much research being done to connect test findings with appropriate treatments.
Sometimes diagnoses overlap when it comes to the brain and this makes treatment complicated. The neuropsychologist must really use his or her skills to identify the most important diagnosis and recognize a proper treatment.
Other diagnoses can be ranked and treated in turn. Some diagnosis can effectively be treated together with the same goal in mind.
Doctorates who practice in the field of experimental neuropsychology are continuing to uncover the relationships between the physical brain and cognitive function
Usually, they work on healthy subjects while the minority of doctorates works on animal subjects. Specific features of the nervous system are isolated out and studied, such as the visual system. In clinical neuropsychology, the management and rehabilitation of people with neurocognitive problems is undertaken.
The parts of the brain are united with the aspect of the personality that has suffered. The brain deficits are practiced until they are improved on and until the psychological aspects of the illness have been similarly improved.
Neuropsychological Assessments are also called NPEs or neuropsychological evaluations are performed by a neuropsychologist, who can gain access to the patient’s motor, cognitive, behavioral, linguistic skills, and executive functioning.
This can tell whether or not a person is suffering from a cognitive deficit or other deficit in brain functioning. The information gathered can tell people if there is an effective treatment strategy in a patient’s rehabilitation.
The NPE provides a great deal of insight into the psychological functioning of the person, better than an imaging test can do.
The NPE must be interpreted by a trained neuropsychologist and combined with clinical reports, physical examinations and premorbid/postmorbid relative reports.
Each test has strengths and weaknesses in being able be valid, reliable, sensitive and specific to the patient. The use of the NPE is increasing quite a bit.
It is a test that helps in many areas including evaluating the following:
- Intellectual functioning
- Language processing
- Academic achievement
- Attention and concentration
- Visuospatial processing
- Visual learning and memory
- Verbal learning and memory
- Speed of processing
- Executive functioning
- Sensory-perceptual functions
- Motor speed and strength
- Personality assessment
- Motivation/symptom validity
- Intellectual function.
