Acute electroconvulsive therapy followed by maintenance electroconvulsive therapy decreases hospital re-admission rates of older patients with severe mental illness.

OBJECTIVES: Electroconvulsive therapy (ECT) is a highly effective treatment for patients with severe mental illness (SMI). Maintenance ECT (M-ECT) is required for many elderly patients experiencing severe recurrent forms of mood disorders, whereas M-ECT for schizophrenia patients is a poorly studied treatment. We report on the outcomes in aged patients with SMI: schizophrenia and severe affective disorders treated by M-ECT of varying duration to prevent relapse after a successful course of acute ECT. The study measured the effectiveness of M-ECT in preventing hospital readmissions and reducing admission days. METHOD: A retrospective chart review of 42 consecutive patients comparing the number and length of psychiatric admissions before and after the start of M-ECT was used. We analyzed diagnoses, previous ECT treatments, number of ECT treatments, and number and length of psychiatric admissions before and after M-ECT. RESULTS: Mean age in our sample was 71.5 (6.9) years. Twenty-two (52%) patients experienced severe affective disorders and 20 (48%) experienced schizophrenia. Patients were administered 92.8 (85.9) M-ECT treatments. Average duration of the M-ECT course was 34 (29.8) months. There were on average 1.88 admissions before M-ECT and only 0.38 admissions in the M-ECT period (P < 0.001). Duration of mean hospitalization stay decreased from 215.9 to 12.4 days during the M-ECT (P < 0.01). CONCLUSIONS: Our findings suggest that acute ECT followed by M-ECT is highly effective in selected elderly patients with SMIs.

Co-morbid social phobia in schizophrenia.

BACKGROUND: The co-morbid occurrence of anxiety disorders and schizophrenia has recently begun to be investigated. Social anxiety may be especially important to diagnose and manage among patients with schizophrenia. AIM: To investigate the prevalence and correlates of social phobia in patients with schizophrenia. METHOD: Diagnosis of schizophrenia and schizoaffective disorders as well as co-morbid anxiety disorders was established according to DSM-IV and the Structured Clinical Interview for Diagnosis (SCID-P Hebrew version). Severity of psychotic symptoms and social anxiety symptoms was assessed with the Positive and Negative Symptom Scale (PANSS) and the Liebowitz Social Anxiety Scale (LSAS). RESULTS: The cohort studied included 117 patients with schizophrenia. Thirteen patients were diagnosed as suffering from co-morbid social phobia (11%). There was a tendency for patients with co-morbid social phobia to have higher severity PANSS total score. There was a significant correlation between the score of the LSAS ;fear' and PANSS positive subscales. Avoidance scores were higher among patients with negative signs. CONCLUSION: Co-morbidity of schizophrenia and social anxiety disorder is not rare among patients with schizophrenia. Treatment implications need be further investigated.

Itching in the psychiatric ward.

Chronic itch is known to have psychogenic elements; however, there is no data on itch prevalence and characteristics among hospitalized psychiatric patients. We investigated the prevalence and types of itching among hospitalized psychiatric patients who met DSM-IV criteria for schizophrenia, affective or other psychiatric disorders. A validated itch questionnaire based on the McGill Pain Questionnaire, which examines the incidence and characteristics of itching, was administered to 111 patients, hospitalized in an Israeli university hospital. Patients with atopic eczema, psoriasis, or systemic diseases that cause pruritus were excluded. Thirty-six patients (32% of those screened) reported itching. Few sought help or used anti-pruritic therapy. Itching should be addressed during psychiatric assessments, in order to provide appropriate treatment.

Quetiapine for elderly non-responsive schizophrenia patients.

Ten elderly chronic schizophrenia patients who were not responding to an atypical antipsychotic were switched to quetiapine. The Brief Psychiatric Rating Scale (BPRS) demonstrated statistically significant improvement after 6 months of quetiapine treatment. Four patients discontinued treatment due to clinical exacerbation or sedation. There was no increase in abnormal movements or body weight.

A randomized, single-blind, comparison of venlafaxine with paroxetine in elderly patients suffering from resistant depression.

It is estimated that up to 45% of patients with depression do not have an adequate response to a first trial of antidepressant therapy with even higher reported rates for the elderly patients. To compare the efficacy and the tolerability of venlafaxine vs. paroxetine in elderly patients suffering from resistant major depression, who did not respond to at least two previous adequate trials of antidepressants. Patients entered an 8-week single-blind study. Patients were rated using the Clinical Global Impression Scale, Hamilton Rating Scale for Depression, and the Geriatric Depression Scale. Assessments were performed at baseline and on days 7, 14, 21, 28, 42 and 56. Side effects were recorded in a systemic manner. Thirty patients were included in the study, (17 women, 13 men; mean age=75.9 years, range: 68-83) and all had completed the 6-week trial. Mean dose of venlafaxine used was 165 mg/day (SD=73.8; range 75-300 mg). Mean dose of paroxetine used was 26 mg/day (SD=15.04; range 10-60 mg). Nine patients treated with venlafaxine (60%) and five patients treated with paroxetine (33%) remitted after 8 weeks of treatment. Four patients treated with venlafaxine and eight patients treated with paroxetine failed to respond. Significant improvement in Hamilton Rating Scale for Depression scores between baseline and endpoint were observed in both groups of patients. The mean Hamilton Rating Scale for Depression change for paroxetine was -12.5 and for venlafaxine -19.1 (P<0.05). The mean Geriatric Depression Scale change for paroxetine was -3.2 and for venlafaxine -6.0 (P<0.3). The mean Clinical Global Impression Scale change was -2.3 for paroxetine and -3.5 for venlafaxine (P<0.05). Venlafaxine was significantly superior to paroxetine on Clinical Global Impression Scale and Hamilton Rating Scale for Depression measures. Side effects were transient and did not differ between treatment groups. Elderly depressed patients resistant to previous treatments had responded to a trial of paroxetine or venlafaxine. Remission rates were higher for venlafaxine and tolerability was acceptable for both compounds.

Cardiac and cerebrovascular morbidity and mortality associated with antipsychotic medications in elderly psychiatric inpatients.

OBJECTIVE: To evaluate the rate of adverse medical outcomes for elderly exposed to antipsychotic treatment. METHODS: This was a retrospective evaluation of psychiatric inpatients records. Age, gender, diagnosis, treatment with antipsychotics, and duration of treatment were analyzed. An acute cardiac or cerebrovascular event necessitating transfer to a general hospital or resulting in death was the outcome measure. RESULTS: During 15 years (1990 to 2005), 3,111 elderly were hospitalized. Their mean age was 73.5 +/- 6.1 years, 1,220 were male (39%), and 1,891 were female (61%). Most patients (2,583 [83%]) were exposed to antipsychotics, of which 1,402 (54%) were exposed to second-generation antipsychotics (SGAs). Antipsychotic-treated patients did not have a higher rate of adverse medical outcomes compared with patients who had not received antipsychotics. No significant differences were noted between patients exposed to typical antipsychotics or SGAs. CONCLUSION: Treatment of elderly psychiatric inpatients with antipsychotics did not increase their risk of adverse medical outcomes. Thus, regulating the use of conventional antipsychotics or SGAs for all elderly patients in all indications may be premature.

Intramuscular ziprasidone treatment of acute psychotic agitation in elderly patients with schizophrenia.

OBJECTIVE: Intramuscular (i.m.) ziprasidone treatment has been shown to be effective and well tolerated in reducing the symptoms of acute psychosis in adults. Few data are available as to safety in the elderly. The growing utilization of health services by elderly psychiatric patients warrants an evaluation in this population. METHOD: Consecutive elderly patients (60 years of and older) admitted to a psychogeriatric ward in a large, university-affiliated tertiary psychiatric center were treated by i.m. ziprasidone for acute psychotic agitation. Patients received three days of flexible-dose i.m. ziprasidone. After an initial dose of 10-20 mg, a subsequent dose of 10-20 mg could be given after 12 hours if needed (maximum daily dose: 40 mg). RESULTS: All treatment emergent side effects and adverse events along with the investigators' assessments of severity were systematically recorded as the primary outcome. The Brief Psychiatric Rating Scale (BPRS) and the Behavioral Activity Rating Scale (BARS) were the secondary outcomes. Twenty-one patients, six male and 15 female, mean age 71.4 +/- 1.3 years (range: 60-81 years) were enrolled. All had completed the three days i.m. ziprasidone treatment. There was one adverse event in a patient with untreated benign prostatic hypertrophy who developed urinary retention. Two side effects of mild severity that resolved spontaneously were observed: blurred vision and sedation. The BPRS decreased by 26.8 points after three days of treatment (p = 0.001). The BARS score, reflecting agitation, decreased significantly after each injection, reaching maximal decrease of 2.14 points at completion of study (p = 0.001). CONCLUSION: Intramuscular ziprasidone in this series of elderly patients suggests acceptable safety and efficacy in the management of acute psychotic agitation among elderly patients with schizophrenia.

Patients with very-late-onset schizophrenia-like psychosis: a follow-up study.

OBJECTIVE: The topic of course and outcome of very-late-onset schizophrenia-like psychosis (VLOSLP) has not received the research attention it deserves. The aim of this study was to evaluate the course of clinical symptoms and functional status of patients with VLOSLP in comparison with patients with life-long schizophrenia. METHODS: Telephone interviews were conducted on primary caregivers of 21 patients with VLOSLP who had recently been released from inpatient care. Their treating staff evaluated 21 schizophrenia inpatients according to the same criteria. RESULTS: The majority of patients with VLOSLP did not present cognitive and functional deterioration. On the other hand, 8 of the 19 patients in the elderly schizophrenia group had some functional decline; 3 of those 8 patients seemed to have some cognitive decline, as well. CONCLUSIONS: The results suggest that the VLOSLP patients present stable cognitive and everyday functioning, as compared with chronically institutionalized elderly patients with schizophrenia.

Venlafaxine for the treatment of depressive episode during the course of schizophrenia.

The emergence of depression in the course of schizophrenia is common and arouses much interest and therapeutic concern. It has been associated with a less favorable prognosis and increased incidence of suicide. However, relatively few treatment studies have been performed in this area. The use of a combination of antidepressants and antipsychotic agents is controversial. We report an open-label study carried out to evaluate the efficacy of the addition of venlafaxine in schizophrenia patients treated with antipsychotics and diagnosed with concurrent depressive episode (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria). Patients (N = 19) who did not show spontaneous improvement after 4 weeks were assigned to a 6-week trial with add-on venlafaxine. Patients were evaluated at a 1-week interval with the Hamilton Depressive Rating Scale, the Positive and Negative Syndrome Scale, and the Clinical Global Impression Scale. All 19 patients had completed the 6-week trial. Fourteen patients (74%) showed significant improvement measured with Hamilton Depressive Rating Scale and Clinical Global Impression Scale. The mean venlafaxine dose was 146 mg/d (range: 75 to 225 mg/d). In most patients, there was a parallel decrease in psychotic symptoms. We conclude that venlafaxine may have a role in the treatment of depression in patients with schizophrenia without causing exacerbation of psychosis.

Donepezil for the treatment of behavioral symptoms in patients with Alzheimer's disease.

Behavioral and psychologic symptoms of dementia (BPSD) are common manifestations in mid- and late-stage Alzheimer's disease (AD). Traditional treatments for BPSD are neuroleptics and sedatives, which are not devoid of serious adverse effects. A number of studies show beneficial effects in the treatment of BPSD with acetylcholinesterase inhibitors (AChEI). The present study aimed to evaluate the effect of donepezil (using the generic drug Memorit) as monotherapy for AD patients suffering from BPSD. Twenty-eight consecutive patients followed at the Memory Outpatient Clinic and Psychogeriatric Department of the Abarbanel Mental Health Center were treated with donepezil for 6 months. Starting dose was 5 mg daily during the first 4 weeks and continuation with 10 mg daily thereafter. Treatment effects were evaluated using the Mini Mental State Examination (MMSE), the Neuro-Psychiatric Inventory (NPI), and the Clinical Global Impression of Change Scale (CGIC) caregiver version. Twenty-four of 28 patients completed the study. Of these, five patients needed additional rescue neuroleptic treatment due to incomplete response. The mean dose of donepezil was 9.10 mg/day (median 10 mg/day). The overall NPI improved significantly from 33.4 to 21.2 (p = 0.008). The mean CGIC at study's end was 3.0 (mild improvement). The cognitive scores did not change significantly. When compared to the patients who completed the study, patients who discontinued had higher mean scores on the irritability and agitation subscales of the NPI, they were older, and they had longer disease duration and lower MMSE mean scores. Three adverse events were recorded: one syncope causing a toe phalanx fracture and gastrointestinal complaints that resolved over time in two additional patients. Acetylcholinesterase inhibitors should be considered for the treatment of BPSD before neuroleptic treatment is instituted in AD patients with low levels of irritability and agitation.

Very late-onset schizophrenia-like psychosis: clinical and imaging characteristics in comparison with elderly patients with schizophrenia.

Studies of late-onset schizophrenia began in the early 1940s with work by M. Bleuler. Despite this fact, the emphasis on age of onset in young adulthood distracted researchers of schizophrenia from accumulating data on the subgroup of patients whose disease onset is in late life. Recently, the diagnostic entity of very late-onset schizophrenia-like psychosis (VLOSLP) was proposed for patients with disease onset after age 60 years, and it may have validity and clinical utility. The present study aims to prospectively identify patients suffering from VLOSLP over a 2-year period and to compare them with elderly schizophrenia patients on measures of brain structure, demographics, and treatment response, so that distinct features, if any, can be identified. Twenty-one VLOSLP patients (15 women, 6 men; mean age, 78.1 years) were enrolled and compared with 21 age- and gender-matched elderly schizophrenia patients. All had undergone brain CT scan, and all were treated with risperidone. The VLOSLP group was characterized by more education, higher percentage being married, more pronounced cerebellar atrophy, and better response to treatment. The authors suggest that VLOSLP is a valid diagnostic entity and that its features imply that involvement of neurodegenerative process may be etiologically relevant to psychosis with onset in late life.
