Self-informant rating concordance for attention-deficit/hyperactivity disorder (ADHD) symptoms was assessed in 281 adults at the subscale (Inattention, Hyperactivity-Impulsivity) and individual symptom levels. Potential demographic, diagnostic, and informant identity moderators were also investigated. Concordance levels were similar for current and childhood symptoms. Although moderate positive correlations were found between self- and informant ratings on both subscales, informants endorsed more significant inattentive symptom severity. Kappa coefficients were variable, suggesting low concordance for certain symptoms. Sex and ADHD diagnosis moderated concordance, although effect sizes were small. These results have implications for the use of behavior rating scales in diagnosing ADHD, raise questions about the validity of self- and informant ratings, and support the need to investigate individual-differences variables that may impact concordance.

The distribution of cholecystokinin (CCK) mRNA in the rat brain was determined by means of in situ hybridization histochemistry. Our results demonstrate a widespread distribution of neurons containing CCK mRNA throughout the rat brain. Hybridization-positive neurons were distributed throughout the neocortex, olfactory bulb, claustrum, amygdala, the dentate gyrus and hippocampus proper, and several subnuclei of the thalamus and the hypothalamus. The most abundant and most heavily labeled neurons were found in the endopiriform/piriform cortex, tenia tecta, and the ventral tegmental area. The distribution of neurons positive for CCK mRNA paralleled that of CCK-like immunoreactive neurons. These results detail the distribution of CCK mRNA and clearly identify the existence of CCK-synthesizing neurons in regions such as the paraventricular and supraoptic nuclei of the hypothalamus, where the presence of CCK cell bodies was previously uncertain.

We examined the ability to produce, repeat, and comprehend emotional prosody in 20 patients with Alzheimer's disease (AD) and in 11 elderly normal control subjects. In addition, caregivers of AD patients completed affective and behavioral measures with reference to the patient. Relative to control subjects, comprehension of emotional prosody was marginally impaired in mildly demented AD patients, whereas production, comprehension, and repetition of emotional prosody were significantly impaired in moderately demented AD patients. The moderately demented patients performed significantly poorer than the mildly demented patients on the production and repetition tasks. In contrast, there was no significance difference between the two groups on the prosody comprehension task. Additional analyses revealed an inverse relationship between the ability to correctly produce and repeat emotional prosody and the frequency of agitated behaviors and depressive symptomatology in moderately demented patients. This latter findings suggests that the inability to communicate emotional message is associated with disturbances in mood and behavior in AD patients. Implications for the management of disruptive behavior in agitated and aprosodic AD patients include the development of caregiver sensitivity to unexpressed emotion and caregiver assistance with emotional expression.

Only half of EVAR patients underwent complete long-term imaging surveillance. However, incomplete imaging could not be linked to any increase in mortality. Further work is required to establish the role and deliverability of EVAR imaging surveillance.

The clinical course of early-onset, dominantly inherited, familial Alzheimer's disease (FAD) was contrasted with late-onset, sporadic Alzheimer's disease (AD). Eight FAD and 23 sporadic AD patients were followed over a mean of 63 months from estimated disease onset. The two groups did not differ notably in duration of symptoms from onset, global disease severity, or degree of cognitive deficits on initial evaluation. The Kaplan-Meier lifetable method was used to assess time from estimated disease onset to dependence in self-care, institutionalization, and death. A greater percentage of FAD patients became dependent in self-care and died earlier than did sporadic AD patients. The lifetable results suggest that FAD may have a more rapid course than dose late-onset sporadic AD.
