Summary
Many elderly strokes are "silent" because symptoms are missed or ignored. This study found that a significant number of these silent strokes had recalled symptoms, highlighting the need for better awareness and stroke prevention education for families.
Area of Science:
- Neurology
- Geriatrics
- Radiology
Background:
- Silent brain infarcts (SBIs) affect 8-28% of the elderly population.
- SBIs are linked to increased risks of stroke and cognitive decline.
- SBIs are typically asymptomatic, but symptom recall issues may confound this.
Purpose of the Study:
- To report cases of incidentally detected acute and subacute strokes.
- To investigate whether these incidentally detected strokes were truly asymptomatic.
Main Methods:
- Utilized MRI from dementia research studies.
- Identified acute/subacute silent strokes using diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) defects.
- Collected clinical data from individuals with incidental DWI lesions.
Main Results:
- Six out of 649 subjects had incidental DWI lesions.
- Three subjects recalled symptoms temporally linked to lesions, which families had dismissed.
- Two subjects presented with focal neurological signs.
- Most subjects with incidental DWI lesions exhibited significant cognitive impairment.
Conclusions:
- A substantial proportion of

01:20Motor Unit Stimulation
4.9K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

01:22Muscle Stimulation Frequency
5.1K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

01:27Regulation of Stroke Volume
6.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

01:22Cardiac Output II: Effect of Stroke Volume on Cardiac Output
4.5K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

01:16Psychosexual Stages of Personality: Latency
1.5K
Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage.
