The human brain's complexity gives rise to various neurodevelopmental and neurocognitive disorders that significantly impact individuals' abilities, behavior, and overall functioning. Understanding these disorders, their diagnostic criteria, causes, and treatment options is essential for advancing clinical practices and improving patient outcomes. This paper explores one neurodevelopmental disorder—Autism Spectrum Disorder (ASD)—and one neurocognitive disorder—Alzheimer’s Disease (AD)—detailing their behavioral criteria, incidence rates, etiological factors, and proposing two diverse treatment approaches for each based on different theoretical models.

Neurodevelopmental Disorder: Autism Spectrum Disorder (ASD)

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized primarily by persistent deficits in social communication and interaction, along with restricted, repetitive patterns of behavior, interests, or activities (American Psychiatric Association, 2013). The behavioral criteria stipulated in the DSM-5 include difficulties in social reciprocity, nonverbal communicative behaviors, and developing, maintaining, and understanding relationships. Individuals with ASD may display repetitive movements, an insistence on sameness, inflexible adherence to routines, and highly restricted, fixated interests (Lord et al., 2020).

According to prevalence data, ASD affects approximately 1 in 54 children in the United States, with a rising trend over recent decades (Maenner et al., 2020). While the exact causes remain unclear, genetic factors play a prominent role, with multiple genes identified that influence neural development and synaptic functioning. Environmental influences, such as prenatal exposure to certain drugs, maternal infections, and advanced parental age, are also implicated (Sandin et al., 2017). The heterogeneity of ASD suggests a multifactorial etiology involving complex gene-environment interactions.

Two effective treatment paradigms grounded in different theoretical models include Applied Behavior Analysis (ABA) and the Developmental, Individual Difference, Relationship-Based (DIR/Floortime) approach. ABA, based on behaviorist principles, emphasizes reinforcement strategies to increase desired behaviors and reduce problematic behaviors (Lovaas, 1987). Conversely, DIR/Floortime, rooted in developmental and relational frameworks, focuses on fostering social engagement and emotional development through play-based interactions that respect the child’s developmental level and individual differences (Greenspan & Wieder, 2006).

Neurocognitive Disorder: Alzheimer’s Disease (AD)

Alzheimer’s Disease (AD) is a progressive neurocognitive disorder characterized by memory impairment, cognitive decline, and functional deterioration. According to the DSM-5, the core features include insidious onset and gradual progression of cognitive deficits interfering with independence in daily activities (American Psychiatric Association, 2013). Behavioral criteria encompass memory loss, disorientation, language difficulties, impaired executive functioning, and changes in personality or behavior, such as agitation and depression (Scheltens et al., 2016).

The incidence of AD increases markedly with age, affecting roughly 6-8% of individuals age 65 and older, with prevalence rising to nearly 30-50% among those over 85 (Prince et al., 2015). The etiology of AD involves multiple factors, including genetic predispositions—most notably the apolipoprotein E (APOE) ε4 allele—and environmental influences such as cardiovascular health, head trauma, and lifestyle factors like diet and physical activity (Reitz et al., 2011). The pathological hallmarks include amyloid-beta plaque accumulation and neurofibrillary tangles, leading to neuronal death and brain atrophy (Selkoe & Hardy, 2016).

Treatment strategies for AD vary based on different theoretical frameworks. Pharmacological interventions, like cholinesterase inhibitors (e.g., donepezil), aim to manage cognitive symptoms—aligned with a biomedical model focusing on neurochemical deficits (Birks, 2006). Cognitive-behavioral approaches, which incorporate psychosocial support and cognitive rehabilitation techniques, are rooted in humanistic and psychosocial models, aiming to enhance quality of life despite neurodegeneration (Livingston et al., 2014). Both approaches underscore the importance of early diagnosis and personalized care plans.

Conclusion

In conclusion, neurodevelopmental and neurocognitive disorders such as ASD and AD exemplify the diverse ways in which brain development and deterioration manifest in behaviors and cognitive functioning. Their diagnostic criteria, causes, and treatments vary widely but can be addressed effectively through multidimensional approaches. Incorporating behavioral, developmental, biomedical, and psychosocial perspectives offers the best chance to improve lives affected by these challenging conditions.
