Summary
Screening for cognitive impairment in older adults lacks sufficient evidence. The US Preventive Services Task Force found the benefits and harms of dementia screening cannot be determined.
Area of Science:
- Gerontology
- Neurology
- Preventive Medicine
Background:
- Dementia, or major neurocognitive disorder, significantly impacts daily independence.
- Prevalence increases with age, affecting millions in the US.
Purpose of the Study:
- To update 2014 recommendations on screening for cognitive impairment.
- To review evidence on screening for mild cognitive impairment and dementia in older adults.
Main Methods:
- Systematic evidence review commissioned by the US Preventive Services Task Force (USPSTF).
- Focused on community-dwelling adults aged 65+ without recognized cognitive impairment symptoms.
Main Results:
- Evidence regarding screening for cognitive impairment was found to be lacking.
- The balance of benefits and harms of such screening could not be determined.
Conclusions:
- The USPSTF issued an "I statement" indicating insufficient evidence.
- Current evidence is insufficient to assess the benefits versus harms of screening older adults for cognitive impairment.

01:30Cognitive Development During Adulthood
694
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
456
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

01:30Dementia
458
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

01:15Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
