Summary
Cognitive impairment frequently complicates stroke, increasing patient dependence. This study highlights the need for better understanding and management of these cognitive issues in stroke survivors.
Area of Science:
- Neurology
- Public Health
- Cognitive Science
Background:
- Stroke presents a significant global health challenge with substantial socio-economic impacts.
- Cognitive complications following stroke remain understudied in many regions, including Chad.
- Understanding these complications is crucial for effective patient management and care.
Purpose of the Study:
- To describe the prevalence and characteristics of cognitive impairment in stroke patients in Chad.
- To provide data that can inform improved management strategies for stroke survivors.
Main Methods:
- A cross-sectional, descriptive, multicenter study was conducted over 8 months in three referral hospitals in Ndjamena.
- 24 stroke patients diagnosed with cognitive impairment (VASCOG criteria) were assessed using various tools including MMSE, Albert test, Rey figure, ISDC, GADS, and Barthel scale.
- Data collected included sociodemographic, anamnestic, clinical, and paraclinical variables.
Main Results:
- 18.18% of the enrolled stroke patients exhibited cognitive impairment.
- Common issues included memory problems (100%), motor deficits (20%), and language disorders (12%).
- Significant findings included perceptual neglect (16%), total dependence in daily activities (41.7%), and moderate depression (41%).
Conclusions:
- Cognitive impairment is a common and significant complication of stroke, directly contributing to increased patient dependence.
- Further research with comprehensive neuropsychological assessments and neuroimaging is recommended to better understand stroke-related cognitive deficits.

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
