Predicting conversion to Alzheimer's disease among individual high-risk patients using the Characterizing AD Risk Events index model.

This study aims to determine whether the Characterizing AD Risk Events (CARE) index model can effectively predict conversion in individuals at high risk for AD development either in an independent aMCI population or in an rLOD population. METHODS: The CARE index model was constructed based on the event-based probabilistic framework fusion of AD biomarkers to differentiate individuals progressing to AD from cognitively stable individuals in the aMCI population (27 stable subjects, 6 progressive subjects) and rLOD population (29 stable subjects, 10 progressive subjects) during the follow-up period. RESULTS: AD diagnoses were predicted in the aMCI population with a balanced accuracy of 80.6%, a sensitivity of 83.3%, and a specificity of 77.8%. They were also predicted in the rLOD population with a balanced accuracy of 74.5%, a sensitivity of 80.0%, and a specificity of 69.0%. In addition, the CARE index scores were observed to be negatively correlated with the composite Z scores for episodic memory (R2  = .17, P

Photo credit Aris Fackenakis The truth, as they see it, is still the truth in their eyes. Delusions, hallucinations, agitation, aggression, and depression are all part of the gradual progression of psychosis of patients with Alzheimer ’s disease (AD). An average of 41% of these patients will experience these psychotic symptoms. One of the most common delusions these patients have are theft-related. An experienced caregiver offers her advice on how to deal with accusations of theft, which are common in dementia patients.

Shutterstock Is it fair to question a presidential candidate’s mental fitness? (Salon): “My heart sank as he floundered his way through his responses, fumbling with his notes, uncharacteristically lost for words. He looked tired and bewildered,” Ron Reagan, the son of President Ronald Reagan, wrote of his father’s performance during the first 1984 presidential debate. At the time, there had long been rumors that Reagan was suffering from cognitive impairment — perhaps Alzheimer’s Disease — and as he struggled during the first debate against his Democratic opponent, former Vice Pres...

Alzheimer's disease (AD) has an estimated prevalence of 50 million persons worldwide1 and an incidence of 10 million cases per year1-3, making it the most common form of dementia. While neuropsychiatric symptoms (NPS) are common in AD, apathy is particularly frequent, affecting up to 70% of patients4. Apathy has been broadly defined as a loss of interest in daily activities and diminished goal directed behavior in the absence of depression and other mood changes5 –7 . This NPS is associated with greater functional impairment, greater caregiver burden, increased risk of institutionalization, poorer quality of life, an...

Abstract 1. Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus infectious disease 2019 (COVID-19), which was first reported in Wuhan, China, in late December, 2019. Despite the tremendous efforts to control the disease, SARS-CoV-2 has infected 1,5 million people and caused the death of more than a hundred thousand people across the globe as of writing. Recently, Mao et al. [1] investigated the penetration potential of SARS-CoV-2 into the central nervous system in 214 patients. They reported that 36.4% of the patients had some neurologic findings which are ranged from nonsp...
