, a prodrome
is an early non-specific symptom
(or set of symptoms) indicating the start of a disease
before specific symptoms occur. For example fever, malaise
, headache and anorexia
(lack of desire to eat) are part of the prodrome for mumps
or a variety of infective disorders. A prodrome can be the precursor to the onset of a chronic neurological
disorder such as migraine
, where prodrome symptoms include scotoma
, disorientation, aphasia
, or photosensitivity.
It also refers to the initial in vivo round of viral replication.
Prodromal labour, mistakenly called "false labour," is the early signs before labour starts.
