"Where Medical Information is Easy to Understand"™
Neuropsychology is a specialty of psychology that studies the relationship between the brain and cognition (thinking), emotions, and behavior. Psychology is the study and profession concerning behavior and the related functions and processes of both the mind and body, in human and non-human animals.
Psychologists who specialize in neuropsychology are known as neuropsychologists. In clinical settings, the practice of neuropsychology involves administering objective tests to patients, the results of which are compared against normal controls. Normal controls are groups of people with no known history of brain damage or other conditions that would reasonably be expected to negatively affect brain functioning. The test results are compared to normal controls of the same age and, when relevant, to those of the same educational background and/or gender. Some tests even allow for patients to be compared against members of their same race/ethnicity, although this practice is somewhat controversial. By comparing test results against normal controls, this allows the neuropsychologist to determine how close or far away the performance is from what would be expected.

Neuropsychological tests generally comprise the following areas: sensori-motor functioning, language, visual-spatial functioning, learning/memory, attention/concentration, processing speed (thinking speed), and executive functioning. Executive functioning is a broad concept that refers to higher level thinking skills such as planning, organization, abstract thinking, response suppression, and multi-tasking. Sometimes, intelligence tests (IQ tests) are administered as are tests of academic achievement (e.g., reading, reading comprehension, spelling, written expression and math). Tests of personality and emotional functioning are generally used as well since problems in these areas can negatively affect thinking skills and mimic or worsen a genuine neurological problem.
Usually, neuropsychology is used to quantify a patient’s pattern of strength and weaknesses in those with a known neurological condition such as traumatic brain injury or multiple sclerosis. Since neuropsychological tests assess different regions of the brain, the test results can indicate if brain functioning is affected in one area more than another. For example, executive functioning is primarily controlled by the frontal lobes (brain tissue in the front part of the brain, behind the forehead). Thus, poor performance on these tests can mean that the frontal lobes are damaged. Since the left hemisphere controls language in most people, poor performance on verbal executive functioning tests can indicate damage to the left frontal lobe. Making such determinations requires a comprehensive integration of the test performance, statistics, knowledge of the patient’s history, behavioral observations, knowledge of the patient’s known or suspected pathological condition, and other factors.

In some cases, neuropsychology is used to help diagnose specific disorders of the brain such as Alzheimer’s disease. The techniques used in neuropsychology can be used with children and adults and can help answer specific questions such as can a patient drive, is a patient disabled, does the patient need academic and/or vocational accommodations, and/or is a patient competent to manage financial matters or make medical decisions, to name a few.
Tests in neuropsychology can be repeated to measure recovery from brain damage or monitor the progression of neurological conditions affecting the brain. Neuropsychology assessments can also be used to develop strategies to rehabilitate (make better) or compensate for existing deficits in neurologically compromised individuals. They can also be used to help guide medical treatment (e.g., medication selection) and to determine if psychological counseling is needed in addition to (or as opposed to) treatment in the physical realm.
Neuropsychology comes from the Greek word "neuron" meaning "nerve," the Greek word "psyche" meaning "mind," and the Greek word "logos" meaning "the study of." Put the words together and you have "the study of (the) mind (and) nerves."
