Description
Chapter 15 LEGEND N= neuropsychologist CN= clinical Neuropsychologist  Before: assessment was to figure out whether there is a brain damage  Now: CT scan and MRI’s quickly locate the damage and the extent of the damage  Clinical neuropsychologist diagnose conditions, assess quality of life and evaluate the client’s capacity to succeed in his or her environment.  Recently more involved in rehabilitation. THE CLIENT  Also called o Patient medical perspective o Participant/ subject research perspective o Client clinical neuropsychologists.  There is no “typical” neuropsychological client  The age and conditions can vary in terms of nervous system damage o In younger people more direct head injuries like motor accidents o In older people result of diseases like dementia, tumour CVA  The event that brought the client into contact with a CN can vary; the setting in which they are assessed and even the goal of the assessment can vary THE NEUROLOGIST  Neurologist a special type of physicist who diagnoses, studies and treats disorders of the NS o These disorders could be of unknown etiology, caused by trauma, infections, tumours, toxins or metabolic disorders o They are trained to perform detailed examination of the neurological structures throughout the whole body o Testing of relatively basic sensory and motor functions o Also some testing of cognitive abilities o Can also administer a lumbar puncture to obtain cerebrospinal fluid for testing o They can recommend surgeries but not perform them o Surgeries are performed by Neurosurgeons.  EDUCATION: o 2- 4 years of pre med university training o 4 years of medical school M.D. (doctor of medicine) OR D.O (doctor of osteopathy) o 3 years of specialty training in a neurology residency program. THE RADIOLOGIST  Are a rare group; only 1.2% of U.S physicians specialize in radiology.  They have specialized training in obtaining and interpreting images of the human body and/or treating conditions using radiological science.  And then writes a detailed report about the findings for the primary care physician or neurologist  EDUCATION: o Just like neurologist premedical, medical and residency in their speciality. THE CLINICAL NEUROPSYCHOLOGIST  Clinical neuropsychology o “Branch of neuropsychology concerned with psychological assessment, management and rehabilitation of neurological disease and injury” o Explaining how behavioural impairments can be explained in terms of damage to the neural component o EDUCATION  Undergraduate B.A or B.Sc in Psych  A Master’s degree in clinical psychology M.A., M.Sc., or M.A.Sc.  Doctorate degree Ph. D. or Psy.D.  Internship  Experimental neuropsychology o Focuses on how human behaviour arises form brain activity  Cognitive Neuropsychology o Focused on explaining behaviour or impairments in terms of functional brain units regardless of their anatomical representation. After an individual suffers from a brain injury:  Physician or emergency room attendant (neurological assessment) Radiologist Neurologist Clinical Neuropsychologist. THE ASSESSMENT  Most people have their first assessment in an emergency room by an emergency room physician  This is not as detailed as a full neuropsychological exam but it gives important insights into the person’s functioning and quickly gaining an estimate of how much the NS is impaired.  Depending on the severity of the injury and the impairment, then they are recommended to a neuropsychologist.  In its most basic form o It’s concerned with reflexes o Medical history o Cranial nerve functioning of the person. o Muscle tone  Depending on the severity, a CT scan or MRI might be done  A neurological test also includes a test called Mini Mental State Exam or Modified Mini Mental State Exam tests the person’s cognitive functioning like memory, language and orientation.  Some people with dementing illnesses or non-traumatic impairment may first seek help from family physician perform the basic tests  Depending on the results might be recommended to a neurologist and further to a Neuropsychologist. NEUROPSYCHOLOGICAL ASSESSMENT  Is the detailed examination of cognitive functioning  Consists of a personal interview and performance on a series of tests  The personal interview includes past medical history and the person’s description of any problems  The tests are standardized in 2 ways: o They are always administered to the participants in the same way o They are always scored in the same manner.  The results of the test are used to help with diagnosis, intervention and rehabilitation.  Some common goals of the assessment: o Provide evidence of cognitive dysfunction o Understand ambiguous results from other assessments o Reveals subtle deficits that might have been missed before o Provides a profile of the individual to document disease progression and plan rehabilitation o Provides insights into the different functions of different areas of the brain o Help determine the reason for the impairment.  TWO APPROACHES BEEN TAKEN IN PERFORMING THE TEST o SELECTION OF TEST DEPENDING ON THE RESON OF ASSESSMENT o FIXED TEST BATTERIES  THE HALSTEAD-REITAN BATTERY  In 1930’s to examine any cognitive change following brain injury  FIVE CORE TESTS: o Category test abstract reasoning or hypothesis testing o Tactual shapes into holes blindfolded o Rhythm similarities and differences between rhythms o Speech sound perception match spoken nonsense words with written o Finger tapping tap index finger as fast as possible for 10 seconds.  PROBLEMS o No di
