Molecular mechanisms underlying cyclophosphamide induced cognitive impairment and strategies for neuroprotection in preclinical models Molecular and Cellular Biochemistry Springer Nature Link Chronic hypoxia leads to cognitive impairment by promoting HIF 2 mediated ceramide catabolism and alpha synuclein hyperphosphorylation Cell Death Discovery Growth factors and their peptide mimetics for treatment of traumatic brain injury ScienceDirect PDF) AngIV Analog Dihexa Rescues Cognitive Impairment and Recovers Memory in the APP PS1 Mouse via the PI3K AKT Signaling Pathway DIHEXA is a neurogenic peptide designed to enhance cognitive function by increasing synaptic density in the brain. Unlike stimulants that offer temporary boosts, Dihexa supports long term brain health improving communication between
