Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a developmental condition characterized by differences in social interaction, communication, and behavior, with a broad range of severity and presentation. The prevalence of ASD has increased in recent years, with current estimates suggesting that approximately 1 in 36 children in the United States are diagnosed, according to the Centers for Disease Control and Prevention (CDC) in 2023. The spectrum is vast, with individuals exhibiting varying degrees of challenges and strengths, often accompanied by unique abilities or sensitivities. A growing concern is
the number of undiagnosed autistic adults, particularly women, who may have gone unrecognized due to the historical underdiagnosis of females and atypical presentations. Recent research has shown that many adults on the autism spectrum may struggle with undiagnosed conditions for years, leading to challenges in mental health, relationships, and employment. As awareness increases, there is a push for better recognition and support for autistic adults, including those who have lived with the condition without a formal diagnosis. Studies, including those by the National Institutes of Health (NIH), continue to focus on the neurodevelopmental basis of ASD, as well as on early interventions and personalized treatment approaches to improve outcomes for all affected individuals.

Neurocognitive Disorders
Neurocognitive disorders (NCDs) refer to a group of conditions characterized by a decline in cognitive function, a:ecting memory, learning, attention, and executive function. These disorders are often seen in aging populations, with Alzheimer’s disease being the most prevalent form, a:ecting an estimated 6.7 million Americans aged 65 and older, according to the Alzheimer’s Association (2023). In South Africa, the prevalence of dementia, a major NCD, is increasing due to an aging population, with approximately 1.3 million South Africans living with dementia, according to the South African Medical Research Council (2021). Other common NCDs include vascular dementia, Parkinson’s disease, and frontotemporal dementia. As the global and local populations age, the prevalence of neurocognitive disorders is expected to rise, creating a growing need for effective treatments. Recent research into treatment options has focused on improving cognitive function and slowing the progression of these diseases. Promising studies, such as those supported by the National Institute on Aging (NIA) and South African research institutions, explore drug therapies, lifestyle interventions, and cognitive training programs aimed at managing symptoms and enhancing the quality of life for patients with NCDs.

Adolescent Psychiatry
Adolescent psychiatry focuses on the mental health needs of individuals between the ages of 12 and 18, a period marked by significant emotional, cognitive, and social development. Common mental health conditions in adolescents include depression, anxiety, conduct disorders, and substance use disorders. In South Africa, the prevalence of mental health issues among adolescents is concerning, with a 2019 study by the South African Medical Research Council (SAMRC) showing that approximately 15% of South African adolescents experience mental health disorders. Depression and anxiety are among the most common conditions, Research has highlighted the need for targeted mental health interventions, with increasing efforts to integrate mental health care into primary health care systems. Additionally, stigma surrounding mental health often prevents many adolescents from seeking help, further contributing to the burden of untreated mental health issues in this age group.

Depression
Depression is a common and serious mental health condition characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in daily activities. It can a:ect anyone, but it is particularly prevalent among adolescents and adults. In South Africa, depression is a major public health concern, with approximately 10% of the adult population affected, according to the South African Depression and Anxiety Group (SADAG) in 2020. Depression is also linked to suicidal ideation, with suicide being a leading cause of death among South African teenagers. Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are commonly prescribed for depression, with research showing that about 60-70% of individuals who take these medications experience significant symptom improvement.

Anxiety
Anxiety disorders are among the most common mental health conditions globally, characterized by excessive worry, fear, and nervousness that can significantly interfere with daily life. In South Africa, it is estimated that 15% of the population experiences some form of anxiety disorder, with generalized anxiety disorder, panic disorder, and social anxiety disorder being the most prevalent. According to the South African Depression and Anxiety Group (SADAG), anxiety disorders have a profound impact on quality of life, leading to impairments in social relationships, work, and academic performance. Individuals with anxiety often experience difficulties in concentrating, fatigue, and a diminished ability to perform daily tasks. The economic impact is also significant, as anxiety disorders are associated with decreased productivity, increased absenteeism, and higher healthcare costs. Globally, anxiety disorders are among the leading causes of disability, and untreated anxiety can lead to a higher risk of developing other mental health conditions, such as depression. Addressing anxiety through timely intervention, including therapy and medication, is crucial to improving the well-being and productivity of individuals affected by these disorders.

Bipolar Disorder
Bipolar disorder is a mental health condition characterized by extreme mood swings, including periods of mania or hypomania (elevated or irritable mood) and depression. It affects approximately 1-2% of the global population, with similar prevalence rates in South Africa. The South African Depression and Anxiety Group (SADAG) estimates that about 1 in 50 South Africans live with bipolar disorder. The condition typically emerges in late adolescence or early adulthood, and while it can be e:ectively managed with medication and therapy, it significantly impacts the lives of those a:ected. People with bipolar disorder often face challenges with maintaining stable relationships, holding down jobs, and managing daily responsibilities due to the unpredictable nature of the mood swings. The lived experience of bipolar patients can involve both the high of mania, which may lead to risky behaviors and impaired decision-making, and the deep lows of depression, which can result in feelings of hopelessness and suicidal thoughts. Treatment, including mood stabilizers and psychotherapy, can help manage symptoms, but many patients still experience stigma and misunderstanding, which can further isolate them and a:ect their overall quality of life.
