CNS infections mark the peak among determinants of brain atrophy. Other conditions that lead to brain atrophy include, space occupying lesions, birth injury, trauma and trivial contribution from drugs and convulsive disorders.
Figure 2: Determinants of Brain Atrophy and their influence
A: Bi-lateral planum sphenoidale meningioma in 16 years boy with extracranial extension through the optic tract resulting into mild cerebral cortical atrophy. B: left frontal scalp abscess with frontal sinusitis with mild cerebral cortical atrophy. C: Left parietal focal brain atrophy in connection with history of trauma. D: White cerebella sign with bitemporal hypoattenuation due to birth asphyxia.
Figure 3: Varying additional determinants of Brain atrophy effects
A: Enlarged lateral ventricles due to severe hydrocephalus with failed shunt. High reading of Evans index >0.3 is evident. B: Brain re-expansion to normal volume or mild atrophy after successful shunt. Borderline sulcal width and ventricular width is shown. C: Severe brain volume loss despite
Figure 4: Hydrocephalus and possible outcomes after interventions ventriculo-peritoneal shunt (VPS) due to delayed intervention. More enlarged cortical sulcal width is shown indicating severe cortical brain atrophy

A: The PCA figure above shows that, Arusha region is affected by all the factors followed by Kilimanjaro region and Manyara. Tanga region is less affected despite its exposure to trivial radiation injury. B: PCA shows that female are exposed more by most contributing factors of brain atrophy compared to male individuals.
Figure 6: Regional and gender distribution of the determinants of brain atrophy
Figure 7: PCA showing distribution of the determinants of brain atrophy among cases and controls The figure above shows exposure distribution of risk factors among the normal and atrophied brain. Most factors point toward the atrophied brain compared to normal brain
