Summary
Cognitive impairments are common after ruptured aneurysm treatment. Anterior cerebral artery aneurysms lead to worse memory and fluency deficits, regardless of other factors.
Area of Science:
- Neurosurgery
- Neuropsychology
- Cognitive Neurology
Background:
- Cognitive deficits following ruptured aneurysm treatment are often underestimated.
- This study aimed to determine the prevalence of cognitive impairments and associated factors.
Purpose of the Study:
- To assess the prevalence of cognitive impairments in patients treated for ruptured anterior circulation aneurysms.
- To analyze factors associated with these cognitive impairments.
Main Methods:
- 87 patients operated on for ruptured anterior circulation aneurysms were evaluated at 3 months post-discharge.
- Cognitive functions including memory and verbal fluency were assessed using continuous scales.
- Univariate and multivariate analyses were performed to identify associated factors.
Main Results:
- Phonemic fluency was impaired in 66% of patients; 56% had memory impairments.
- Anterior cerebral artery (ACA) aneurysm treatment was linked to significantly greater recent and remote memory deficits (P < 0.05).
- ACA aneurysms also showed greater phonemic fluency impairments (P = 0.04), independent of other factors.
Conclusions:
- Cognitive impairments are frequent after ruptured anterior circulation aneurysm treatment.
- Patients treated for ACA-related aneurysms experience significantly worse memory and phonemic fluency deficits.
- These findings highlight the need for targeted cognitive assessment and management post-treatment.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

01:21Coronary Circulation
7.4K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

01:19Overview of Pulmonary Circulation
3.3K
The pulmonary circulation is a vital system in our body that acts as a bridge between the respiratory and cardiovascular systems. It serves as a transport network for deoxygenated blood from the heart to the lungs and then returns oxygen-rich blood back to the heart.
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
