Substance misuse and cognitive functioning in early psychosis: a 2 year follow-up

High comorbidity exists between substance use and psychosis. Since substance use has been shown to negatively impact cognitive functioning in the general population, there is concern about the impact of substance use on already compromised cognitive functioning. However, the literature regarding the effects of substance use on cognition in early psychosis patients is inconclusive. The purpose of this study was to examine the relationship between substance misuse and cognitive functioning in a first episode psychosis sample for 2 years following admission to a specialized early psychosis program. One hundred and eighty-three subjects were assessed at baseline, 147 at 1 year and 116 at 2 years using the Case Manager Rating Scale (CMRS) for substance use and a comprehensive cognitive battery. Approximately 50% of subjects engaged in substance misuse at baseline, which did decrease over follow-up. At baseline, the cognitive performance of patients with both mild use and misuse was significantly better than non-users. These same patients demonstrated better performance at follow-up. These results do not provide evidence for a negative impact of substance use on cognition.     

Outcome after discharge from an early psychosis program

Studies defining the course and outcome of individuals experiencing their first episode (FE) of psychosis generally report an improvement in symptoms and functioning. Today, many FE patients are treated in specialized early psychosis programs. Little is known what happens to these individuals after discharge from these programs back to regular services. We report here on the outcomes of the first 200 subjects admitted to a three year specialized first episode service who could be contacted for assessments between 1 and 2 years after discharge. Approximately 50% of those initially assessed in a first episode service were able to be followed for up to 5 years. Results were that, although there was no further improvement in positive symptoms, there was continued improvement in social functioning and signs of improvement in negative symptoms.     

Duration of untreated psychosis predicts treatment outcome in an early psychosis program

For patients first presenting with a non-affective psychotic disorder, the duration of untreated psychosis (DUP; the time between the onset of positive psychotic symptoms and the initiation of appropriate treatment) varies widely, from a few weeks to several years. A number of studies report that a longer DUP is associated with poorer clinical outcomes. We studied DUP and its association with clinical outcomes in a group of patients with schizophrenia and related psychotic disorders treated in the naturalistic clinical setting of an early psychosis program. DUP was determined for 19 patients with a non-affective psychotic disorder (schizophrenia, schizoaffective disorder or schizophreniform disorder) and no previous treatment for psychosis, by use of the IRAOS, a retrospective structured interview carried out with patients and their families. Positive and Negative Syndrome Scale (PANSS) and Global Assessment of Function (GAF) ratings were available at baseline and 6month follow-up. For analysis, patients were categorized into a short DUP (n=9) or long DUP (n=10) group. The median DUP (57weeks) was used as the dividing point. At baseline, the two groups did not differ significantly on positive symptoms or total PANSS ratings. However, negative symptoms were more severe in the long DUP group at baseline (P=0.029), and the long DUP group had a significantly higher mean rating for the passive/apathetic social withdrawal item of the PANSS (P=0.024). At 6month follow-up, the long DUP group had significantly higher ratings for positive symptoms (P=0.028) and had lower GAF scores (P=0.044). Significantly more (P=0.033) long DUP patients had enduring positive psychotic symptoms. The results confirm both the wide range of DUP among patients first presenting with schizophrenia and related psychotic disorders and the association of long DUP, defined as greater than approximately 1year, with a poorer clinical outcome. This study highlights the importance of collecting data regarding DUP and supports the view that patients with a long DUP are likely to be less responsive to treatment in general and will require greater resources and more intensive interventions.     

Impact of an early psychosis program on substance use

Approximately 37% of admissions to a recently developed program for first episode patients met criteria for substance abuse or dependence as well as criteria for one of the schizophrenia spectrum disorders. In this program the issue of substance use is addressed at the initial assessment and throughout the program. Several intervention strategies are integrated within the range of available psychosocial treatments. Additionally, we offer a specifically designed treatment strategy. This paper describes our 2-year experience with an integrated approach to reduce substance use in a specialized treatment program for individuals experiencing a first episode of psychosis.     

Symptom outcome 1 year after admission to an early psychosis program.

OBJECTIVE: To determine the change in positive, negative, and depressive symptoms after 1 year in an early psychosis program. METHOD: One hundred and eighty subjects were included from the first 257 admissions for a first episode of psychosis to a comprehensive early psychosis program. Most had a diagnosis of schizophrenia or schizophreniform disorder. Subjects were assessed on admission to the program and at 3, 6, and 12 months after admission. All 180 subjects completed the 1-year assessment. Assessment measures included the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia. RESULTS: There was a clinically and statistically significant improvement in positive symptoms by 3 months, depression increased at 3 months but significantly improved by 12 months, and negative symptoms changed little over the first year. CONCLUSIONS: The differential changes in symptoms in the first year after admission have implications for treatment.     

Substance use and cognition in early psychosis

OBJECTIVE: To determine the relation between substance use and cognition in individuals experiencing their first episode of psychosis. DESIGN: Prospective cross-sectional and longitudinal study. SETTING: An Early Psychosis Treatment and Prevention Program, an outpatient clinic in a psychiatry department at a university-affiliated hospital. PARTICIPANTS: Individuals with a psychotic illness who were admitted to an Early Psychosis Program; 266 patients were assessed at initial presentation, 159 at 1 year and 90 at 2 years. Most were outpatients. MEASURES: The effects of substance use (alcohol, cannabis, hallucinogens, cocaine, stimulants) on cognition were assessed. Substance use was determined by DSM-IV criteria, and the Case Manager Rating Scale was used to determine the level of substance use. A comprehensive cognitive battery of tests was used, and the Positive and Negative Syndrome Scale for schizophrenia was administered to all subjects to determine levels of positive and negative symptoms. RESULTS: Overall, both cross-sectionally and longitudinally, there were no significant associations between cognitive functioning and the use of various substances. Substance use was associated with higher positive symptoms. CONCLUSIONS: Individuals with psychotic disorders who show mild-to-moderate abuse of substances, in particular alcohol and cannabis, do not exhibit more cognitive impairment than those who do not do use the substances. However, substance use may have other detrimental effects on the process of the psychotic illness.     

Three-year outcome of family work in an early psychosis program

At the initial presentation to a first-episode of psychosis program, family members were experiencing distress and difficulties. The purpose of the study was to assess the effectiveness of individualized family intervention integrated within a comprehensive treatment program for first episode psychosis. Participants were the family members of individuals who had presented with a first episode of psychosis. Family members were assessed with the Psychological General Well-Being Scale and the Experience of Caregiving Inventory (ECI). Patient data included assessment of positive and negative symptoms, depression, quality of life, and substance use. Assessments were conducted over a three-year period. Over time families demonstrated improved psychological well-being and ECI scores. The most significant predictor of poor psychological well-being was the family's appraisal of the impact of the illness on themselves and not the severity of symptoms or impaired functioning. This family intervention embedded within a treatment program proved to be highly acceptable and effective.     

Substance abuse and related diagnoses in early psychosis

Substance abuse seems to be common among those with early signs of evolving psychosis. This article seeks to determine the prevalence of substance abuse and substance use disorders (SUDs) and the association of abuse and SUD with vulnerability psychosis among a sample of first-degree relatives of schizophrenic patients (n = 70), help-seekers (n = 29), and control subjects (n = 34). The Structured Interview for Prodromal Symptoms (SIPS) 1.0 was used to define the vulnerability status and the Structured Clinical Interview for DSM-IV Axis I to diagnose the subjects. Data on various other measures, including premorbid adjustment, personality disorder symptoms, psychological distress, and abuse of substances, were collected. Those who were identified as vulnerable to psychosis reported significantly more lifetime alcohol abuse and had more commonly an SUD than controls. Substance use disorder, as well as alcohol and drug abuse, correlated significantly with personality disorder symptoms and current positive SIPS score and both types of abuse also with disorganization SIPS score. The odds ratio for having an SUD among those vulnerable to psychosis was 6.33 (95% confidence interval, 1.77-22.73). Early psychosis and substance abuse frequently occur together.     

Substance misuse over the first 18 months of specialized intervention for first episode psychosis

Aim: Examine substance misuse over the first 18 months of first‐episode psychosis treatment. Method: Clinicians rated alcohol and drug (mostly cannabis) misuse for 243 individuals followed prospectively. Assessments were completed at baseline and after 3, 6 and 18 months. Interventions relating to substance misuse included ongoing assessment of use, education and counselling to avoid. Results: Alcohol and drug misuse declined significantly between baseline and 3 months, especially among patients with a substance abuse or dependence diagnosis at baseline. Overall, these reductions were maintained over the 18‐month follow‐up period. The exception was worsening alcohol misuse over time among patients with alcohol abuse or dependence on entry. Conclusions: With good usual care, education and support, alcohol and drug misuse declined significantly during the first months of psychosis treatment. The improvements in drug misuse were generally maintained over the 18‐month follow‐up, and worsening alcohol misuse over time may be the greater issue.     

Clinical outcome of an early psychosis intervention program: evaluation in a real-world context

OBJECTIVE: To examine whether staff training and service restructuring to provide specialized early psychosis services results in improved clinical outcomes for young people with first-episode psychosis. METHOD: Staff attended workshops on the treatment of early psychosis throughout 1997-2000 and specialized early psychosis teams began operating between 1998 and 2000 following service restructure. There was no additional funding provided for clinical services, but through the restructure, there was a shift in resources. During this period a comprehensive package including the Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms and the Health of the Nation Outcome Scale was introduced for clinicians to assess patients at intake, 3 months and 12 months into treatment. Symptom scores of patients treated earlier in the project are compared with those patients treated later, after more training and service developments had occurred. RESULTS: Ninety-four of 215 potential first-episode patients consented to take part in the project. They provided data variously at intake, 3 months and 12 months into treatment. Regardless of the year of treatment, significant improvement in psychiatric symptomatology was found over the three assessment periods. Individuals who entered the service in the latter phase of the project experienced fewer negative symptoms (after 12 months of treatment) compared with patients who entered the service in the early phase of the project. CONCLUSIONS: Improvements in both pharmacological and possibly psychosocial treatment may have led to a greater improvement in negative symptoms. Benefits and limitations of conducting research in a "real-world" context are discussed.     

Employment status amongst those with psychosis at first presentation

Introduction  

Employment is generally beneficial to health and quality of life. Despite many advances in the treatment of psychosis there are continuing reports of high levels of unemployment. In most studies of first episode psychosis (FEP) only rudimentary rates of employment are provided. We sought to establish the prevalence of employment amongst those with FEP from a geographically defined area, to compare employment categories for differences in demographical and clinical characteristics and finally, to examine factors associated with employment.     

Suicidality prior to presentation in first-episode psychosis

Introduction: Suicide and attempted suicide contribute significantly to the increased mortality and morbidity associated with psychotic illness. The period of highest risk is reportedly in the early years of illness. While the literature concentrates on completed suicide in chronic psychosis, less is understood about attempted suicide in first‐episode psychosis (FEP). Aim: We aimed to examine rates and correlates of suicide attempts in individuals with FEP. Method: Individuals in this study were all those, both in‐ and outpatients, diagnosed with FEP over a 2‐year period, from a defined catchment area. Assessment included Structured Clinical Interview for DSM‐IV, Schedule for Assessment of Positive Symptoms, Schedule for Assessment of Negative Symptoms, Calgary Scale, Beiser Scale and Birchwood Insight Scale. Results: Of 107 patients with FEP, 50 (47%) individuals reported suicidal ideation: 41 (38%) in the month prior to first presentation. Ten individuals (9%) made a suicide attempt. The only factor significantly associated with previous suicide attempt was higher insight scores at first presentation (P = 0.04). Conclusion: Individuals with a history of suicide attempt tend to have higher insight into having a mental illness at first presentation.     

Risk of suicide and suicidal ideation in psychosis: Results from an Italian multi-modal pilot program on early intervention in psychosis

Suicidality is high in schizophrenia, particularly in first-episode patients. Little is known about patients with prodromal symptoms of psychosis or otherwise high-risk persons.In a sample enrolled in an early intervention program implemented in Milan (Italy), a history of attempted suicide before enrollment was found in 6 first-episode schizophrenia (out of 87, 6.9%), and 7 high-risk of psychosis (out of 81, 8.6%) patients.In the first-episode group, a history of suicide attempts was related to a shorter duration of untreated psychosis. In the high-risk group, a family psychiatric history in first/second degree relatives of patients and a personal history of substance abuse were both associated with an enhanced risk of attempted suicide before enrollment.During the first year of treatment, 3 new attempted suicides were recorded among 57 (5.3%) high-risk patients, and none among first-episode patients (n = 58) (no dropout in the sample). The levels of suicide ideation on the BPRS did not differ by group at assessment, and significantly declined from assessment at entry to 1-year follow-up, except in seven HRP patients who become positive for core symptoms of schizophrenia, as measured on the BPRS.At enrollment, patients at high risk of psychosis had the same prevalence of past suicide attempts than first-episode schizophrenia patients: since suicide attempt is the most important predictor of a future suicidal attempt, the assessment of suicide risk should be given a privileged role in patients at high risk of psychosis as well.     

Substance misuse and psychiatric comorbidity in adolescents

PURPOSE OF REVIEW: Many young people are misusing and becoming dependent on multiple substances (especially nicotine, alcohol, and cannabis), with a complex variety of psychological effects. RECENT FINDINGS: Analysis of interactions between smoking, drinking, and cannabis use indicates that the relationship between substance use and psychiatric comorbidity is primarily explained by regular smoking. In some studies the use of cannabis on a regular basis was associated with an increased risk of psychiatric illness. This is by no means the case for all studies, so this area of work remains controversial. Children with attention deficit hyperactivity disorder who are substance misusers have a poorer prognosis than those without it so there is concern about treatment with stimulant drugs: this fear appears not to be substantiated by one study. Young people with anxiety disorders are at increased risk of substance use disorders. Clinical trials for adolescent substance abuse treatment have provided support for the benefits of cognitive behavioural interventions. There is an accumulating evidence base for pharmacological treatment for adult substance misusers that can inform treatment for younger patients. It is estimated that, of those adolescents who were likely to be in need of help, only about 9% received treatment. SUMMARY: Since psychiatric disorders beginning in childhood may continue into adult life, there is an opportunity to intervene to prevent or reduce conditions complicated by substance misuse, if services are accessible. The need for longitudinal work is vital to explore the patterns of comorbidity, and implement and evaluate appropriate treatment interventions.     

Substance abuse in first-episode non-affective psychosis

Abuse of alcohol and drugs is an important and clinically challenging aspect of first-episode psychosis. Only a few studies have been carried out on large-sized and reliably characterized samples. These are reviewed, and the results are compared with a sample of 300 first-episode psychosis patients recruited for the TIPS (Early Treatment and Identification of Psychosis) study from Norway and Denmark. Prevalence rates from the literature vary from 6% to 44% for drugs and 3% to 35% for alcohol. In our sample, 23% abused drugs and 15% abused alcohol during the last 6 months. When compared to non-abusers, the drug-abusing group is characterized by the following: male gender, younger age, better premorbid social, poor premorbid academic functioning, and more contact with friends in the last year before onset. Alcohol abusers were the oldest group and they had the least contact with friends. A group of patients abusing both drugs and alcohol had poor premorbid academic functioning from early childhood. Overall, drug and alcohol abuse are highly prevalent in contemporary first-episode psychosis samples. In our study, substance abuse comorbidity did not generate differences on diagnosis, duration of untreated psychosis, psychiatric symptoms, or global functioning at onset/baseline. The premorbid profiles of the substance abusers were clearly different from the non-abusers. Drug abusers, in particular, were more socially active both premorbidly and during the year preceding the start of treatment.
