Schizophrenia is a chronic psychiatric disorder that cannot be cured, but effective treatment is essential to reduce symptoms and improve functioning. The illness often follows a fluctuating course, with alternating periods of remission and relapse (American Psychiatric Association, 2023).
Positive symptoms such as hallucinations, delusions, and thought disorder are generally responsive to antipsychotic medication. Treatment aims not only to reduce acute psychotic symptoms but also to prevent relapse and enhance quality of life. In contrast, negative symptoms – including apathy, diminished initiative, and blunted affect – are more resistant to treatment and are strongly associated with long-term disability (Galderisi et al., 2018).
Pharmacological Treatment
Antipsychotic medication has been central to schizophrenia treatment since the 1950s. First-generation antipsychotics were effective but often caused severe extrapyramidal side effects. Second-generation (atypical) antipsychotics generally carry a lower risk of motor adverse effects, but they may induce metabolic complications such as weight gain, diabetes, dyslipidemia, and a general sense of malaise (Leucht et al., 2013). These side effects significantly contribute to treatment discontinuation and poor adherence (Kane et al., 2019).
Approximately 20–30% of patients show insufficient response to standard antipsychotics, a condition referred to as treatment-resistant schizophrenia (TRS) (Howes et al., 2017). The causes of TRS are complex and not fully understood, though genetic, neurobiological, and treatment-related factors are implicated. Clozapine remains the gold-standard treatment for TRS, though even here, a proportion of patients fail to respond adequately (Siskind et al., 2021).
The Role of Family and Psychosocial Interventions
Family support plays a crucial role in adherence and structuring daily life. Psychoeducational family interventions have been shown to reduce relapse rates and improve overall outcomes (Pharoah et al., 2010).
Psychosocial approaches such as Cognitive Behavioral Therapy (CBT) have demonstrated modest but meaningful benefits in reducing residual symptoms and improving coping (Wykes et al., 2008). Early intervention services also show promise, with evidence that shorter durations of untreated psychosis are associated with improved prognosis (Marshall et al., 2005). However, the degree of long-term benefit and the most effective intervention models remain under investigation.
Multidisciplinary and Holistic Care
Effective treatment goes beyond pharmacology. Multidisciplinary teams, day centers, rehabilitation services, and creative therapies (e.g., art and music therapy) contribute to recovery by enhancing social functioning, resilience, and overall quality of life (Fusar-Poli et al., 2020). A holistic approach integrating medical, psychological, and social support is widely recommended in modern psychiatric care.
Conclusion
While schizophrenia cannot be cured, comprehensive treatment combining pharmacological therapy, psychosocial interventions, and family involvement significantly improves outcomes. For patients who do not respond to first-line antipsychotics, clozapine and multidisciplinary approaches offer renewed possibilities for stabilization and improved quality of life.
