____________________ Alzheimer’s Disease and Dementias: Insights for Early Detection and Care Planning
INTRODUCTION Dementia, including Alzheimer disease, is a significant and growing concern globally, particularly among the elderly population. According to the World Health Organization (WHO), more than 55 million people worldwide are living with dementia, and this number is expected to rise to 88 mil- lion by 2030 and 139 million by 2050 [1]. Alzheimer disease is the most common form of dementia, accounting for 60% to 70% of cases. In the United States alone, the Alzheimer’s Association reports that more than 6 million Americans older than 65 years of age are living with Alzheimer disease, a num- ber projected to reach nearly 13 million by 2050 [2; 3]. This condition not only leads to a progressive decline in cognitive function, severely impacting memory, thinking, and social abilities, but also places a substantial emotional, physical, and financial burden on families and caregivers. Early detection and diagnosis are crucial for managing symptoms, planning for the future, and improving the quality of life for those affected. Understanding the different types of dementia, their symptoms, and the importance of early intervention is essential for providing compassionate and effective care to those living with these conditions.
OVERVIEW OF DEMENTIA Dementia is a term for a decline in cognitive function severe enough to interfere with daily life and activities [4; 5]. It includes symptoms affecting memory, thinking, and social abilities, making everyday tasks challenging. Dementia is a syndrome resulting from various conditions, such as Alzheimer disease, vascular dementia, Lewy body dementia, and fron- totemporal dementia. Each type has unique symptoms and progression, but common signs include memory loss, difficulty with problem-solving, impaired judgment, and changes in behavior and personality ( Table 1 ).
TYPES OF DEMENTIA
Disease
Symptoms
Attributes/Causation
Parkinson disease
Poor executive function Trouble walking, unstable gait Impaired responsiveness to visual cues Speech impairment Impaired affect/modified facial expression Decreased eye blinking Depression Confusion Insomnia Rigidity/freezing, tremor Alzheimer disease traits (memory loss, confusion, and language changes) Frontal lobe brain cell damage due to nerve damage Diagnosis confirmed postmortem Drastic change in behavior and personality Aggression Loss of speech Loss of decision-making ability Loses sense of self-awareness Patient will become completely dependent Progressive dementia Affects ability to think, reason, and process information Impaired movement, mood, and behavior
Basal ganglia cells die, causing dopamine levels to drop Progressive, chronic disease Personalized treatments for symptom relief Exercise can improve symptoms and may protect the brain No cure
Frontotemporal dementia (FTD)
Frontal lobe controls language and personality Also known as Pick disease No cure
Lewy body dementia (LBD)
1.4 million people living with this disease Due to unusual deposits of alpha-synuclein protein on brain Initial diagnosis may be mental/psychological health No cure
Parkinsonian-like rigidity Hallucinations, paranoia
