 Meningitis due to Haemophilus influenza, Streptococcus pneumoniae and Meningococci: immunisation.

Generally, where primary causes are poorly understood, causation can be divided into

 predisposing factors (e.g. age, gender, genetic susceptibility)

 enabling factors (e.g. hypertension, poor nutrition, inadequate medical care)

 precipitating factors (e.g. exposure to infectious or noxious agent)

 reinforcing factors (e.g. repeated or prolonged exposure).

Most neurological conditions are products of multifactorial influences, each of which alone would not cause the disease. It is thus helpful to study risk factors.
