Prognosis
Identification of poor prognostic factors include cerebral edema, status epilepticus, and thrombocytopenia. In contrast, a normal encephalogram at the early stages of diagnosis is associated with high rates of survival. Epidemiology
The number of new cases a year of acute encephalitis in Western countries is 7.4 cases per 100,000 people per year. In tropical countries, the incidence is 6.34 per 100,000 people per year. The number of cases of encephalitis has not changed much over time, with about 250,000 cases a year from 2005 to 2015 in the US. Approximately seven per 100,000 people were hospitalized for encephalitis in the US during this time. In 2015, encephalitis was estimated to have affected 4.3 million people and resulted in 150,000 deaths worldwide. Herpes simplex encephalitis has an incidence of 2–4 per million of the population per year. Terminology
Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis.The word is from Ancient Greek ἐγκέφαλος, enképhalos "brain", composed of ἐν, en, "in" and κεφαλή, kephalé, "head", and the medical suffix -itis "inflammation".

75% of all suicide attempts are by drug overdose, a method that is often thwarted because the drug is nonlethal, or is used at a nonlethal dosage. These people survive 97% of the time. Repetition
A nonfatal suicide attempt is the strongest known clinical predictor of eventual suicide. Suicide risk among self-harm patients is hundreds of times higher than in the general population. It is often estimated that about 10–15% of people who attempt suicide eventually die by suicide. The mortality risk is highest during the first months and years after the attempt: almost 1% of individuals who attempt suicide will die by suicide if the attempt is repeated within one year. Recent meta-analytic evidence suggests that the association between suicide attempt and suicidal death may not be as strong as it was thought before. Outcomes
Suicide attempts can result in serious and permanent injuries and/or disabilities. 700,000 (or more) Americans survive a suicide attempt each year. People who attempt either hanging or carbon monoxide poisoning and survive can face permanent brain damage due to cerebral anoxia. People who take a drug overdose and survive can face severe organ damage (e.g., liver failure). Individuals who jump from a height and survive may face irreversible damage to multiple organs, as well as the spine and brain. While a majority sustain injuries that allow them to be released following emergency room treatment, a significant minority—about 116,000—are hospitalized, of whom 110,000 are eventually discharged alive. Their average hospital stay is 79 days. Some 89,000, 17% of these people, are permanently disabled.
