A survey of deep learning for MRI brain tumor segmentation methods: Trends, challenges, and future directions
ConclusionThis review's objective is to increase scholars' interest in this difficult field and familiarize them with current advancements in it. To create CAD systems aimed at brain tumor identification using MR images, digital image processing approaches, such as preprocessing, segmentation, and classification, are applied. The classic machine learning and deep learning approaches for brain tumor identification are deliberated in this work. This paper provides a summary of commonly used MR image datasets. For classification, various machine learning and deep learning algorithms have been used. This survey examines curren...

Forecasting prevalence and mortality of Alzheimer's disease using the partitioning models
This study uses 5 %-Medicare data (1991-2017) to identify, partition, and forecast age-adjusted prevalence and incidence-based mortality of AD as well as their causal components.METHODS: The core underlying methodology is the partitioning analysis that calculates the relative impact each component has on the overall trend as well as intertemporal changes in the strength and direction of these impacts. B-spline functions estimated for all parameters of partitioning models represent the basis for projections of these parameters in future.RESULTS: Prevalence of AD is predicted to be stable between 2017 and 2028 primarily due ...

Dietary energy restriction in neurological diseases: what’s new?
AbstractEnergy-restricted diet is a specific dietary regimen, including the continuous energy-restricted diet and the intermittent energy-restricted diet. It has been proven effective not only to reduce weight and extend the lifespan in animal models, but also to regulate the development and progression of various neurological diseases such as epilepsy, cerebrovascular diseases (stroke), neurodegenerative disorders (Alzheimer's disease and Parkinson's disease) and autoimmune diseases (multiple sclerosis). However, the mechanism in this field is still not clear and a systematic neurological summary is still missing. In this...

Nasu-Hakola Disease With Stroke-like Attack: A Case Report
Alzheimer Dis Assoc Disord. 2023 Feb 20. doi: 10.1097/WAD.0000000000000547. Online ahead of print.ABSTRACTHomozygous mutations in the triggering receptor expressed on myeloid cells 2 (TREM2) gene are known to cause Nasu-Hakola disease, which is a rare cause of progressive presenile dementia. A 36-year-old woman presented with repetitive seizures, a 5-year history of progressive behavioral and cognitive changes, and an affected sibling. Magnetic resonance imaging of the brain revealed an ischemic lesion in the left medial temporal lobe. Extensive evaluation of juvenile stroke revealed that viral and autoimmune encephalitide...
