Age and Ageing
|December 19, 2014
Summary
Older adults experiencing syncope (fainting) or unexplained falls show poorer cognitive performance. This study highlights a link between these events and cognitive decline in individuals aged 50 and over.
Area of Science:
- Gerontology
- Neurology
- Epidemiology
Background:
- Syncope and unexplained falls are common in older adults.
- Cognitive impairment is a growing concern in aging populations.
- The relationship between syncope/falls and cognitive function requires further elucidation.
Purpose of the Study:
- To compare cognitive performance in older adults with and without a history of syncope or unexplained falls.
- To investigate the association between syncope/falls and cognitive function in a large, population-representative sample.
- To determine if age modifies the relationship between syncope/falls and cognitive performance.
Main Methods:
- Utilized data from the Irish Longitudinal Study on Ageing (TILDA).
- Compared cognitive performance (Montreal Cognitive Assessment - MoCA score) between participants with and without syncope/unexplained falls in the past 12 months.
- Employed multivariate linear regression analysis, controlling for potential confounders.
Main Results:
- Analyzed data from 5,846 participants (median age 62).
- A history of syncope and/or unexplained falls was significantly associated with lower MoCA scores (B=-0.4; P=0.006) after adjustment for confounders.
- Higher syncope burden showed an association with lower cognitive performance, though largely explained by confounders. No age interaction was observed.
Conclusions:
- Older adults with recent syncope or unexplained falls exhibit poorer global cognitive performance.
- The study did not find an age-related effect on the association between syncope/falls and cognitive function.
- Further research is needed to establish a causal relationship between syncope burden, unexplained falls, and cognitive decline.

01:22Dementia l: Introduction
3
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

01:29Hepatic Encephalopathy
18
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

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.

01:30Negative and Cognitive Symptoms of Schizophrenia
1.1K
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

01:07Narcolepsy
841
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
