When the energy centers of brain immune cells stop working properly, those cells become inflammatory and cause damage to the brain's protective lining and to brain cells themselves.
See the scientific wording
Mitochondrial dysfunction in microglia causes these cells to adopt a pro-inflammatory (M1) phenotype, which in turn disrupts the blood-brain barrier and damages neurons.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Microglial Mitochondrial Dysfunction and Neuroinflammation
Comprehensive search of databases for studies on microglial mitochondrial dysfunction, M1 polarization, blood-brain barrier integrity, and neuronal damage, with meta-analysis of effect sizes.
Randomized Trial of Mitochondrial-Targeted Therapy on Microglial Phenotype and Neurological Outcomes
Randomized, double-blind, placebo-controlled trial in patients with conditions associated with microglial mitochondrial dysfunction (e.g., neurodegenerative diseases), comparing a mitochondrial-targeted drug vs placebo, measuring microglial activation markers, blood-brain barrier integrity (e.g., MRI), and cognitive/neurological outcomes over 12 months.
Prospective Cohort Study of Mitochondrial Dysfunction and Neurodegenerative Outcomes
Prospective cohort of patients with mitochondrial disorders vs matched controls, followed for 5-10 years, with periodic assessments of microglial activation (PET imaging), blood-brain barrier permeability (CSF albumin ratio), and cognitive decline.
Case-Control Study of Microglial Mitochondrial Function in Neuroinflammatory Disease
Retrospective study comparing post-mortem brain tissue or CSF samples from patients with neuroinflammatory disease vs controls, measuring mitochondrial respiratory chain activity, microglial markers (Iba1, CD68), and evidence of blood-brain barrier damage.
In Vitro Study of Mitochondrial Inhibition in Microglia and Inflammatory Response
Culture of human or mouse microglia, treat with mitochondrial inhibitors (e.g., rotenone, antimycin A) or knock down mitochondrial genes, then measure M1 markers (iNOS, TNF-α), and co-culture with brain endothelial cells and neurons to assess barrier integrity and neuronal viability.
