ALS Anxiety: 18% State, 14% Trait in 433 Patients

MHD featured image for anxiety and depression in amyotrophic lateral sclerosis.

In 433 non-demented amyotrophic lateral sclerosis (ALS) patients, clinically significant anxiety was present in 18.2% for state anxiety and 13.9% for trait anxiety. The strongest predictor was not motor severity, cognition, or caregiver-rated behavior; it was depression, especially cognitive-affective depression symptoms.1 Research Highlights ALS anxiety was measurable but not universal: Aiello et al. found clinically …

Olfactory MRI Radiomics Link pTau217 to Alzheimer’s Cognition

MHD featured image for olfactory MRI radiomics, pTau217, and Alzheimer's disease cognitive impairment.

A 2026 multi-cohort Alzheimer’s disease study found that MRI radiomics from the hippocampus and amygdala linked plasma pTau217 and smell identification to cognitive impairment — with more added cognitive signal than simple regional volume. The result is useful because it points to a possible bridge between blood biomarkers and brain-circuit damage, but it is still …

iSupport-Malaysia Dementia Caregiver Program Scored 74.3 on Usability

A 2026 mixed-methods preprint found that iSupport-Malaysia, a multimedia web-based dementia caregiver psychoeducation program, reached a good System Usability Scale score of 74.3. That is enough to justify pilot testing, but not enough to claim caregiver mental-health benefit: 33.3% of usability-test participants failed sign-up, 20.0% failed search, and Loh et al. did not measure burden, …

Multiple Sclerosis Iron MRI Linked to Cognitive Impairment in 12 Studies

MHD featured image for multiple sclerosis, iron-sensitive MRI, and cognitive impairment.

A 2026 systematic review of advanced neuroimaging in multiple sclerosis narrowed 600 database records to 12 studies and found the clearest cognition signal in basal ganglia iron-sensitive MRI measures, while thalamic susceptibility was more variable and often tangled with atrophy. Research Highlights Basal ganglia signal was strongest: across 12 studies, elevated susceptibility or iron-related metrics …

Tau Oligomers Disrupted Nuclear Lamina in Alzheimer’s Disease Models

MHD featured image for tau oligomers, nuclear lamina disruption, and Alzheimer's disease models.

A 2026 Acta Neuropathologica study found that oligomeric tau was linked to early nuclear lamina disruption in Alzheimer’s disease tissue, PS19 tauopathy mice, and human induced pluripotent stem cell (iPSC)-derived neurons.1 The strongest claim is mechanistic: tau oligomers appeared to deform the nuclear envelope and disturb chromatin before overt neurodegeneration, but the work does not …

NDST3 Suppression Restores Lysosome Acidity in Alzheimer’s Mouse Models

MHD featured image for NDST3 suppression and lysosomal acidification in Alzheimer's disease models.

A 2026 mechanistic Alzheimer’s study found that suppressing NDST3 shifted lysosomal pH in APP695Swe neuronal cells from 5.6 back below 5.0, then reduced amyloid-β, MAPT/tau pathology, neuronal injury, and memory deficits in 3xTg-AD mice.1 Research Highlights Lysosome pH moved back down: APP695Swe-overexpressing HT22 cells had lysosomal pH around 5.6, while NDST3 knockdown re-acidified lysosomes to …

C9orf72 ALS Poly-GR Drives Ferroptosis via Nrf2-Slc7a11

MHD featured image for C9orf72 ALS poly-GR and ferroptosis biology.

A 2026 Cell & Bioscience study found that poly-GR, one of the toxic dipeptide-repeat proteins produced in C9orf72-linked amyotrophic lateral sclerosis (ALS), pushed motor neuron-like cells toward ferroptosis: 4-HNE lipid peroxidation rose at p < 0.0001, labile Fe²+ rose at p < 0.001, and erastin caused more cell death in poly-GR-expressing cells than in control …
