Research demonstrates that hundreds of genetically diverse causes of autism dysfunction converge on common molecular pathways during early brain development. This finding suggests potential shared therapeutic targets despite the genetic heterogeneity of autism spectrum disorder.
Alzheimer's disease and epilepsy frequently co-occur and share common pathogenic mechanisms involving AMPA-type glutamate receptors. Perampanel, an FDA-approved AMPAR antagonist for seizure management, may offer therapeutic benefits in patients with comorbid AD-epilepsy, particularly those with myoclonus or sleep disturbances, though clinical evidence remains limited.
This prospective study of 476 traumatic spinal cord injury patients found that 47% also had concomitant traumatic brain injury, with 85% being mild cases. Risk factors for co-occurring injuries included history of substance abuse, motor vehicle accidents, high-energy mechanisms, and tetraplegia rather than paraplegia.
This umbrella systematic review synthesized 20 systematic reviews to assess the prevalence and correlates of mental illness in traumatic spinal cord injury patients, finding depression (up to 43%), PTSD (up to 62%), anxiety (27%), and hazardous alcohol use (≥50%) as major concerns. Common risk factors included pain, injury severity, low social support, and maladaptive coping, though evidence for effective interventions was limited.
This review examines whether Alzheimer's disease and major depressive disorder share common pathophysiological mechanisms, particularly through reduced TGF-β1 cytokine levels and amyloid-beta accumulation. The authors discuss emerging evidence that certain antidepressants (SSRIs, SNRIs, ketamine) may have neuroprotective effects, though they note the evidence remains inconsistent and potentially adverse effects require further investigation.
