The retina shares prominent similarities with the brain and thus represents a unique window to study vasculature and neuronal structure in the brain non-invasively. This protocol describes a method to study dementia using retinal imaging techniques. This method can potentially aid in diagnosis and risk assessment of dementia.

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. The progression of dementia is generally gradual.

Dementia l: Introduction
0 Views •
2026
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...

This article describes the 4 Mountains Test (4MT), a hippocampus-dependent test of working allocentric spatial memory. The hippocampus is affected early in Alzheimer's disease (AD) and this article outlines the 4MT methodology and results of patient testing, which demonstrates the value of the 4MT in the diagnosis of pre-dementia AD.

Assessing Social Dominance in Mouse Models Using the Tube Test

2025
This protocol describes a behavioral assay to evaluate social dominance in rodents using the tube test. Social dominance remains stable over time, and several models of developmental and neurological disorders exhibit robust social dominance abnormalities. Therefore, the tube test serves as a convenient outcome measure for mechanistic studies or preclinical therapeutic screening.
FAQs
Abnormal accumulation of proteins such as tau or TDP-43 can accompany the deterioration of nerve cells and their connections in FTD. Genetic and other causes also contribute to disease risk, so the biological pathway is not identical in every person. This variability helps explain why researchers investigate both protein-related mechanisms and inherited factors when studying disease onset and progression.
FTD may first appear through altered personality, behavior, decision-making, or social cognition rather than prominent memory problems. Those changes can resemble psychiatric symptoms, making the pattern and progression clinically important. Psychological evaluation helps examine whether executive-function difficulties, language changes, and social-cognitive disruption fit a neurodegenerative process rather than representing only a psychiatric condition.
Damage affecting frontal and temporal brain regions can disrupt executive function, social cognition, and speech. Executive difficulties influence planning and decision-making, while language changes can interfere with communication. Because these abilities may change before memory declines, their assessment provides information that a memory-focused evaluation alone might miss and helps clarify the cognitive profile associated with the disorder.
A neuropsychological assessment examines patterns in abilities that are particularly relevant to FTD, including executive function, social cognition, speech, and memory. Clinicians can use the resulting profile to support diagnostic reasoning and distinguish FTD-related changes from psychiatric conditions or other dementias. The assessment also contributes to care planning by identifying affected areas of functioning.
Assessment findings can show how changes in decision-making, behavior, language, or social cognition affect everyday functioning. This information supports care planning by clarifying which abilities need attention and how communication or independence may be affected. In this way, psychological evaluation connects observed cognitive and behavioral changes with practical planning for ongoing support and quality of life.
Research on FTD seeks biomarkers and treatments that may preserve communication, independence, and quality of life. Biomarker work aims to improve understanding or identification of the disorder, while treatment research focuses on protecting meaningful abilities as neurodegeneration progresses. These goals are especially relevant because symptoms may involve behavior and language before memory decline becomes prominent.
