Controlled word association test (CWAT) The CWAT is mentioned in Chapter 27. The patient is asked to say as many words as they can think of starting with particular letters (F, A, S; Benton, 1973). Proper nouns and the same words with different endings (hat, hats) are discounted. Purpose – to assess word fluency Scoring - at the bedside the clinician expects at least 10 words in one minute. In more formal testing, the total number of words generated from the three exercises is determined. This number is then adjusted for age and years of eduction. From the adjusted scores the percentile is calculated. Adjustment Formula: Controlled Word Association Test Adjusted Formula: Female Education Age Age Age Years Completed 25-54 55-59 60-64 Less than 9 +9 +10 +12 9-11 +6 +7 +9 12-15 +4 +5 +7 More than 16 - +1 +3 Adjustment Formula: Male Education Age Age Age Years Completed 25-54 55-59 60-64 Pridmore S. The Set Test This test is mainly used with persons 65 years and over (Isaacs and Kennie, 1973). The patient is asked to name as many items as they can (to a maximum of 10) from each of 4 categories (colours, animals, fruits, towns). Purpose – a test of verbal fluency Scoring – the total is determined. For people of 65 years or over, 95% achieve scores of 15 or over – less is considered abnormal. Digit span Digit span testing has been mentioned in tests of concentration (Chapter 26 – Higher Cortical Functions). This procedure has been operationalized in the Weschler Adult Intelligence Scale (Weschler, 1955). The test has two parts (Digits Forwards; Digits Backwards). In Digits Forwards the patient is to repeat the digits said by the examiner, in Digits Backwards the patient is to reverse the digits (surprisingly). When a patient fails two attempts at one level, the test ceases. Purpose – a test of verbal memory and concentration. Scoring – this is a complicated matter and the examiner must refer to the WAIS manual. However, Lezak (1976) states, “In the general population, all but a few elderly can recall four digits forwards and three reversed…The average adults raw score of eleven is most often based on six digits forwards and five backwards” (page 209).

Studies have demonstrated markedly increased signs of “soft neurological signs” which parallel psychopathology in both schizophrenia and bipolar disorder (Whitty et al, 2006; Zhao et al, 2012). OCD is also associated with significantly greater soft neurological signs than healthy controls (Jaafari et al, 2012). NEUROLOGICAL SOFT SIGNS – HEIDELBERG MANUAL The Heidelberg Manual is one of the leading standardized neurological soft sign examination systems. It has been kindly made available to the DOP by the authors. Johannes Schröder Section Geriatric Psychiatry University of Heidelberg Voss Str. Patients with a history of neurological disorders, drug abuse, or alcoholism are to be excluded from examination. The examination procedure is so chosen that the initial tests are carried out with the patient in a standing position. The patients´ ability to perform a given exercise is scored: 0: Patient has no, or inconspicuous difficulty with the exercise. In an otherwise normal performance (score=0), clear body side differences are quantified by score=1. Gait The gait is judged after a distance sufficient that the patient walks at his normal pace - thus preferably before the examination, as the patient walks to the room. Pay attention to the patients´ dynamics, stride length, and coordination, as well as for exaggerated, reduced, or asymmetrical arm movements. Tandem walking Patient instruction: "Placing one foot directly before the other, try to walk in a straight line. The walking distance should be at least three meters. The exercise is to be performed firstly with open, and repeated with closed eyes. Possible problems: balance disorders, snaking path, feet not placed directly before each other. Right/left orientation The patient and examiner stand facing each other, arms length apart. Verbal instructions to the patient: a) "Touch your right upper arm with your left index finger. Immediate self-correction of errors with (c) or (d). In case, during the further examination, a right/left orientation is observed, it should be evaluated on the above scale. Arm-holding test The test is demonstrated by the examiner, who explains: "Please stand with your legs together, arms straight ahead, elbows straight, palms upwards, fingers splayed, and close your eyes. Finger-to-nose test Directly after Test 4: "Keeping your eyes closed, touch the tip of your nose with your right index finger; now with your left finger. With open eyes, however, the exercise is performed with ease. Instruction: "Keeping your arms straight ahead, make a fist with your right hand and open your left hand wide. Now pull your arms back to your chest and make fists with both hands; extend your arms straight again and open wide your right hand. Now keep repeating this action, alternately opening the other hand. The patient should aim for the fastest possible tempo. Usually, the exercise needs to be demonstrated several times. Pay attention to the tempo and rhythm, and for faltering, re-starting, and to whether the arms are fully stretched.

For example, deficits in psychosis (reviewed later), there is still marked heterogeneity memory, abstraction, and attention are more severe than of recovery of cognitive functioning immediately after the deficits in verbal or perceptual skills (124). In a cross-sectional persistent social and vocational decline in the first psychotic comparison of Raven Progressive Matrixes scores (a valid episode.

Middle Course of Schizophrenia Until the early 1990s, the characteristics of schizophrenia in patients older than 55 years were largely the subject of speculation. As of 1993, it was estimated that less than 5% of all of the research ever performed on patients with schizo- phrenia had included any patients older than 55 years (129). It was 'common knowledge' that by age 55 to 60 years the illness has run its course, psychotic symptoms had burned out, and most patients did not need or did not benefit from medications. Since the early 1990s, however, Time until first admission a substantial amount of research on this topic has been completed, with this area one of the fastest developing as- FIGURE 47.
