Introduction

Dementia is a progressive neurodegenerative disorder that primarily affects cognitive functioning, but its impact extends beyond memory loss and impaired reasoning. Among the most challenging aspects of dementia are the behavioral and psychological symptoms, collectively referred to as BPSD. These symptoms include agitation, aggression, anxiety, depression, hallucinations, and sleep disturbances. BPSD affects the quality of life of patients and significantly increases the burden on caregivers and healthcare systems. Understanding BPSD is crucial for developing effective management strategies and improving overall patient care.[1].

The prevalence of BPSD is high, with studies indicating that nearly 90% of individuals with dementia experience one or more behavioral or psychological symptoms during the course of their illness. These symptoms can emerge at any stage but often intensify as the disease progresses. The manifestation of BPSD varies widely among patients, reflecting differences in dementia type, disease severity, comorbidities, and individual personality traits. Recognizing early signs of BPSD allows for timely interventions that can prevent escalation and reduce distress for both patients and caregivers.[2].

The underlying causes of BPSD are multifactorial, including neurobiological changes, environmental factors, and unmet psychosocial needs. Neurochemical imbalances in the brain, particularly involving acetylcholine, serotonin, and dopamine, contribute to symptoms such as agitation and hallucinations. Environmental stressors, such as unfamiliar surroundings, sensory overload, or lack of meaningful engagement, can trigger or exacerbate these symptoms. Additionally, physical discomfort or untreated medical conditions may manifest as behavioral disturbances, underscoring the importance of comprehensive assessment. [3].

Assessment and diagnosis of BPSD require a holistic approach that considers both medical and psychosocial factors. Clinicians often use standardized tools, such as the Neuropsychiatric Inventory (NPI) or the Behavioral Pathology in Alzheimer’s Disease Rating Scale (BEHAVE-AD), to evaluate the severity and frequency of symptoms. Accurate assessment is essential not only for guiding treatment but also for differentiating BPSD from other psychiatric or medical conditions that may present with similar behaviors, such as delirium, depression, or anxiety disorders.[4].

Management of BPSD typically involves a combination of non-pharmacological and pharmacological strategies. Non-pharmacological interventions are recommended as the first-line approach and include structured activities, environmental modifications, cognitive stimulation, caregiver education, and psychosocial support. These interventions aim to reduce triggers for behavioral disturbances and enhance the patient’s sense of security and engagement. When symptoms are severe, persistent, or pose a risk to safety, pharmacological treatment may be considered, including antipsychotics, antidepressants, or mood stabilizers, but these must be used judiciously due to potential side effects. [5].

Conclusion

Behavioural and psychological symptoms of dementia (BPSD) represent a significant but often under-recognized aspect of dementia care. Effective management requires a comprehensive approach that integrates accurate assessment, personalized interventions, pharmacological prudence, and strong caregiver support. By addressing the complex interplay of biological, psychological, and environmental factors, healthcare professionals can mitigate the impact of BPSD, enhance patient well-being, and reduce caregiver burden. Ongoing research and continued awareness remain vital in ensuring that individuals with dementia receive compassionate, evidence-based care that addresses both cognitive and behavioral challenges.
