Abstract: OBJECTIVE: To provide initial information on the safety and efficacy of the atypical antipsychotic zotepine in the treatment of behavioural and psychological symptoms of dementia (BPSD). METHODS: This was an open-label, single-centre field study. Twenty-four patients with BPSD associated with Alzheimer's disease (n=12) or other forms of dementia (n=12) were included. During the 8-week observation period, the patients received zotepine (Nipolept) [12.5-150 mg/day] for the psychotic components of BPSD; no other treatment interventions for BPSD were allowed. At baseline, day 28 and day 56, patients were evaluated using the Clinical Global Impressions (CGI) scale; the Mini-Mental State Examination (MMSE), the Syndrome Brief Test (SKT) and the Age Concentration Test (AKT) to assess cognition; and the Neuropsychiatric Inventory (NPI) and the Cohen-Mansfield Agitation Inventory (CMAI) to assess BPSD. General adverse effects and, more specifically, the emergence of extrapyramidal symptoms were also assessed. RESULTS: There was no change from baseline to day 56 in the CGI score and the caregiver burden (as indicated by the caregiver-related section of the NPI). There was also no change in cognition (as assessed by the MMSE, SKT and AKT). The neuropsychiatric symptom score according to part 1 of the NPI (especially key psychotic symptoms, aggression and disinhibition) and the CMAI scores improved by 36% and 15%, respectively, between baseline and the end of the study in a highly statistically significant fashion. No significant differences in treatment response or adverse effect profile were noted between the 12 patients with Alzheimer's disease and the 12 patients with other types of dementia. Zotepine was well tolerated, with tiredness and sedation (five and four cases, respectively) being the most frequent complaints. No clinically significant emergence of extrapyramidal symptoms was seen. CONCLUSIONS: Zotepine appears to be well tolerated and effective in treating BPSD, consistent with the performance of other atypical antipsychotic drugs in this condition. Larger, controlled studies are warranted.

Abstract: BACKGROUND: Preliminary evidence suggests that demented patients may experience beneficial effects of light therapy. The authors tested whether bright light therapy (BLT) is capable of improving cognitive functions in patients with Alzheimer-type dementia (AD) or vascular dementia (VD). METHODS: Twenty-three patients with AD or VD were randomly assigned to either evening BLT or dim light therapy (DLT). Effects of light therapy on cognitive functions were assessed before and after light therapy using Mini-Mental State Examination (MMSE) scores. Body temperature rhythm (BTR) was additionally recorded pre- and posttreatment. RESULTS: Irrespective of their diagnosis, patients treated with BLT (p =.0012) but not with DLT (p =.73) showed a statistically significant increase in MMSE total scores after light therapy. Evening BLT simultaneously induced a significant phase delay of 56 min on BTR (p =.025). CONCLUSION: Our preliminary results suggest that short-term evening BLT may exert beneficial effects on cognitive functioning in patients with dementia.

Abstract: Cerebrolysin (Cere) is a compound with neurotrophic activity which has been shown to be effective in the treatment of Alzheimer's disease (AD) in earlier trials. The efficacy and safety of repeated treatments with Cere were investigated in this randomized, double-blind, placebo-controlled, parallel-group study. One hundred and forty-nine patients were enrolled (76 Cere; 73 placebo). Patients received i.v. infusions of 30 ml Cere or placebo 5 days per week for 4 weeks. This treatment was repeated after a 2-month therapy-free interval. Effects on cognition and clinical global impressions were evaluated 4, 12, 16, and 28 weeks after the beginning of the infusions using the Clinical Global Impression (CGI) and the Alzheimer's Disease Assessment Scale-cognitive subpart (ADAS-cog). All assessments, including the 28-week follow-up visit were performed under double-blind conditions. At week 16, the responder rate of the Cere group was 63.5% on the CGI, compared to 41.4% in the placebo group (P < 0.004). In the ADAS-cog, an efficacy difference of 3.2 points in favour of Cere was observed (P < 0.0001). Notably, improvements were largely maintained in the Cere group until week 28, 3 months after the end of treatment. Adverse events were recorded in 43% of Cere and 38% of placebo patients. Cere treatment was well tolerated and led to significant improvement in cognition and global clinical impression. A sustained benefit was still evident 3 months after drug withdrawal.

Abstract: OBJECTIVE: To obtain a cross-sectional overview of therapeutic practice concerning non-cognitive, behavioral signs and symptoms of dementia (BPSD) in Germany, Austria, and Switzerland. METHOD: We selected 24 psychiatrists (8 from each country) for a questionnaire-based survey with 28 detailed practical questions. RESULTS: Attitudes and preferences were in line with the state of the art as documented in the literature, with the exception of the fact that 30 % of the physicians favored a too brief therapeutic trial with selective serotonin re-uptake inhibitors (SSRIs) for agitation. According to the international literature the preferred treatment of psychotic symptoms in Parkinsons's disease is also a little bit different. Modern atypical antipsychotics, and particularly risperidone, were highly favored for agitation, delirium, psychotic symptoms, and rage outbursts; benzodiazepines (oxazepam and lorazepam), and to an extent also low-potency conventional antipsychotics, were favored only for brief ad hoc medication courses. Anxiety and depressive symptoms were preferentially treated with SSRI, with the exception of short-term therapy of generalized anxiety where benzodiazepines were favored. Benzodiazepines and zolpidem were favored for insomnia without pronounced nocturnal agitation. CONCLUSION: Psychiatrists at memory clinics in German-speaking Europe have therapeutic attitudes and practices that are consistent with the current state of the art.

Abstract: INTRODUCTION: Bright light therapy (BLT) is becoming increasingly popular as an adjunct in the treatment of non-SAD depression and circadian rhythm disturbances in demented patients. Although the rate of side-effects is low, special attention should be paid when treating new groups of patients. We present the case of an 80-year-old woman suffering from dementia of Alzheimer's type (DAT). METHOD: Bright light (2.500 lux) was administered two hours daily between 10 and 12 a.m. for 14 days. Changes in delusion or agitation were recorded using the confusion rating scale (CRS). RESULTS: Out of five patients, three already had delusional symptoms which slightly improved during the course of BLT, one patient never showed delusions before or during BLT, and one patient, which we present here, showed an increase in agitation and developed delusional symptoms. After eight days of treatment, the patient developed conjunctival irritation with marked red eyes and complained about blurred vision. After 12 days of treatment, the patient was disorientated in time and place and after 14 days the patient started to hallucinate and BLT had to be discontinued. The paranoid delusions and hallucinations stopped one day after treatment discontinuation. CONCLUSION: Looking at all the presented evidence, BLT seems to be a useful treatment supplement in DAT patients, when suffering from delusions or agitation. On the other hand, caution should be used when using BLT in demented patients if agitation develops or increases during BLT.
