Aย —ย Alcohol: intoxication (drunk), or withdrawal, including DT’s
Eย —ย Epilepsy (seizures from any cause) or Encephalopathy (brain derangements)
I ย ย —ย Insulin:ย Hypoglycemia (low blood sugar), or Hyperglycemia (high sugar)

Iย ย —ย Infectionย (meningitis, pneumonia, sepsis, etc. etc.)
Pย —ย Psychiatric
