Summary
Patients with Alzheimer's disease (AD) show lower cognitive insight, specifically in self-reflectiveness and self-certainty, compared to healthy individuals. This study highlights altered insight in AD patients.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Clinical Neurology
Background:
- Alzheimer's disease (AD) is a progressive neurodegenerative disorder impacting cognition.
- Cognitive insight, the capacity to understand one's own mental state, is crucial for managing illness.
- The cognitive insight profile in AD patients remains largely unexplored.
Purpose of the Study:
- To investigate the cognitive insight profile of patients with probable Alzheimer's disease (AD).
- To compare cognitive insight measures between AD patients and healthy controls.
- To explore the relationship between cognitive insight and other clinical variables in AD.
Main Methods:
- A cohort of 30 probable AD patients and 15 healthy controls participated.
- Participants completed the Beck Cognitive Insight Scale (BCIS), Hamilton Rating Scale for Depression (HAMD), and Hospital Anxiety and Depression Scale (HADS).
- Statistical analyses, including group comparisons and regression, were performed.
Main Results:
- AD patients exhibited significantly lower mean scores on BCIS-self-reflectiveness (BCIS-R) and BCIS-self-certainty (BCIS-C) compared to controls.
- No significant difference was found in the BCIS reflectiveness-certainty index between groups.
- A positive correlation was observed between hallucinations and BCIS-C scores in AD patients.
Conclusions:
- This is the first study to examine cognitive insight in probable AD using the BCIS.
- Patients with probable AD demonstrate significantly impaired self-reflectiveness and self-certainty.
- Findings suggest that cognitive insight deficits are a feature of Alzheimer's disease.

01:29Alzheimer Disease l: Introduction
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...
01:26Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

01:22Dementia l: Introduction
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...
01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:22Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
01:21Cognitive Learning
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
