A consistent map in the medial entorhinal cortex supports spatial memory

Nature Communications
The medial entorhinal cortex (MEC) is hypothesized to function as a cognitive map for memory-guided navigation. How this map develops during learning and influences memory remains unclear. By imaging MEC calcium dynamics while mice successfully learned a

The effect of a training programme stimulating language functions on Alzheimer-type dementia and maintenance of language skills

Aktualności Neurologiczne, 2017
In dementia of the Alzheimer’s type, memory and language impairments coexist, occur early and aggravate with time. The aim of this study was to assess the effect of our proprietary language function stimulating programme on cognitive functions and the ...

Endogenous murine tau promotes neurofibrillary tangles in 3xTg-AD mice without affecting cognition

Neurobiology of Disease, 2014
Recent studies on tauopathy animal models suggest that the concomitant expression of the endogenous murine tau delays the pathological accumulation of human tau, and interferes with the disease progression.

Effects of intensive lifestyle changes on the progression of mild cognitive impairment or early dementia due to Alzheimer’s disease: the need for rigor

Alzheimer’s Research & Therapy
We consider the recent publication by Ornish and colleagues and the rigor expected for interventional clinical trials. We contend that lifestyle intervention trials should strive for the same rigor as drug trials and highlight opportunities to improve ...

Attitudes toward clinical trials across the Alzheimer’s disease spectrum

Alzheimer’s Research & Therapy, 2017
Background Research has revealed that manifest Alzheimer’s disease (AD) dementia is preceded by preclinical and prodromal phases during which pathology is accumulating but function remains intact.

Aging exacerbates development of cerebral microbleeds in a mouse model

Journal of Neuroinflammation, 2018
Background Cerebral microhemorrhages (CMH) are commonly found in the aging brain. CMH are also the neuropathological substrate of cerebral microbleeds (CMB), demonstrated on brain MRI. Recent studies demonstrate the importance of systemic inflammation in

Functional MRI Assessment of Task-Induced Deactivation of the Default Mode Network in Alzheimer’s Disease and At-Risk Older Individuals

Behavioural Neurology, 2009
Alzheimer’s disease (AD) is the most common form of dementia in old age, and is characterized by prominent impairment of episodic memory. Recent functional imaging studies in AD have demonstrated alterations in a distributed network of brain regions ...

The role of thyroid hormones in Alzheimer's disease: Associations with cerebrospinal fluid biomarkers and diagnostic performance

Journal of Alzheimer's Disease Reports
Background The relationship between serum thyroid function indicators and cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) pathology, as well as their diagnostic value in dementia differentiation, remains poorly understood in individuals ...

Time-based and event-based prospective memory in autism spectrum disorder: The roles of executive function, theory of mind, and time-estimation [PDF]

, 2012
Prospective memory (remembering to carry out an action in the future) has been studied relatively little in ASD. We explored time-based (carry out an action at a pre-specified time) and event-based (carry out an action upon the occurrence of a pre ...

Practitioner review: Short-term and working memory impairments in neurodevelopmental disorders: diagnosis and remedial support [PDF]

, 2006
Background: This article provides an introduction to current models of working and short-term memory, their links with learning, and diagnosis of impairments. The memory impairments associated with a range of neurodevelopmental disorders (Down’s syndrome,
