Perhaps you are reading this because you saw the title and a question came up in your mind: is my rather erratic short-term recall a symptom of a more serious problem? Many, if not most, readers ask similar questions as did the twenty-nine Villagers filling the Community Room on Monday, June 29, when the Village hosted a presentation on dementia by Dr. Nikita Maniar, MD, MBA of UCLA Health. Her talk provided a clear, comprehensive overview of dementia and addressed its medical complexity. She also engaged extensively with many excellent questions from Villagers.

Dr. Maniar is a board-certified neurologist and Fellow of the American Academy of Neurology. She completed her medical degree at St. George’s University and her neurology residency at the University of Missouri–Kansas City. Her clinical expertise spans general neurology and several subspecialties, including Alzheimer’s disease, Parkinson’s disease, Long COVID, and headache disorders.

A central theme was clarification that dementia is not a single disease but a syndrome, a collection of symptoms resulting from damage to brain structures responsible for memory, language, reasoning, and behavior. These impairments are significant enough to interfere with daily functioning. Symptoms may include memory loss, language difficulties, impaired judgment, disorientation, and challenges completing familiar tasks. Behavioral and psychological changes are also common, such as anxiety, depression, irritability, agitation, hallucinations, paranoia, and sleep disturbances.

Dr. Maniar emphasized that dementia encompasses several distinct disorders, each with different underlying causes and clinical presentations. Alzheimer’s disease is the most common form and is characterized by abnormal protein accumulation in the brain that progressively impairs cognitive function. Frontotemporal dementia (FTD) primarily affects the frontal and temporal lobes and often presents with early changes in personality, behavior, or language rather than memory loss. Vascular dementia results from reduced blood flow to the brain, often due to strokes or chronic vascular disease, making cardiovascular risk factors such as hypertension, diabetes, and smoking particularly important. Lewy body dementia involves abnormal protein deposits that can cause fluctuating cognition, visual hallucinations, sleep disturbances, and motor symptoms similar to Parkinson’s disease. Mixed dementia, in which more than one pathology is present - commonly Alzheimer’s disease combined with vascular changes - is also frequently observed.

An important diagnostic category discussed was Mild Cognitive Impairment (MCI), which represents a transitional stage between normal aging and dementia. Individuals with MCI experience measurable cognitive decline but are generally able to maintain independence in daily activities. While not all individuals with MCI progress to dementia, the condition is clinically significant because it may signal early neurodegenerative changes. Early identification allows for closer monitoring and risk-factor modification.

Dr. Maniar also reviewed key risk factors and warning signs. Age remains the strongest risk factor, but cardiovascular health, diabetes, hypertension, smoking, and genetic predisposition can also be significant. Early symptoms that warrant medical evaluation include frequently repeating questions, difficulty recalling recent conversations, word-finding problems, trouble managing familiar tasks, disorientation in known environments, and noticeable changes in judgment or personality. She stressed the importance of distinguishing between normal age-related forgetfulness and a progressive pattern of decline that interferes with independence.

Although there is currently no cure for most forms of dementia, Dr. Maniar highlighted that treatment options and supportive strategies have expanded significantly. Pharmacologic treatments, particularly cholinesterase inhibitors such as donepezil, rivastigmine, and galantamine, may provide modest benefit in Alzheimer’s disease. Additional medications may be used to address associated symptoms such as depression, anxiety, or severe behavioral disturbances, though these are applied cautiously.

Dr. Maniar emphasized non-pharmacologic interventions as a cornerstone of care as equally important. Cognitive stimulation, structured physical activity, social engagement, and environmental modifications can all help maintain function and reduce behavioral symptoms. Communication strategies and caregiver education are essential components of effective long-term management. The overarching goal of treatment, she noted, is not only to address symptoms but to preserve dignity, independence, and quality of life for as long as possible.

A significant portion of the presentation focused on planning for the future. Dr. Maniar encouraged early discussions about advance care planning, ideally when individuals can still participate fully in decision-making. Key considerations include establishing healthcare and financial powers of attorney, completing advance directives, planning for driving safety, organizing financial affairs, and assessing home safety. She also highlighted the value of rehabilitation services, including occupational, physical, and speech therapy, in supporting continued independence.

Dr. Maniar further underscored the importance of multidisciplinary, specialized dementia care. Coordinated programs that integrate neurology, rehabilitation, caregiver support, and research opportunities can provide more comprehensive and individualized care. Such programs also help families navigate the emotional and logistical challenges of a dementia diagnosis, which can otherwise feel overwhelming.

The session was particularly well received because Dr. Maniar combined scientific rigor with clarity and responsiveness. She addressed audience questions in depth, tailoring her explanations to the interests and expertise of those present. As one attendee, Jocelyn Keene, observed, Dr. Maniar “was quite clear in her explanation of different forms of dementia, but the best part was the thoroughness of her answers to the many interesting Villager questions.”
