The prodomol phase or phase 1 is an early phase that occurs before the symptoms of psychosis develop. It can last several months, though the length varies. There are vague signs that “things are not quite right” and people may experience mild or infrequent symptoms. Because psychosis often begins during adolescence, it is often difficult for family members and professionals to differentiate between the normal struggles of youth and the early warning signs of psychosis. This first phase involves symptoms that may not be obvious, such as changes in feelings, thoughts, perceptions and behaviours.
Common prodromal symptoms
reduced concentration and attention
changes in energy level
less interest in usual activities
no longer going to school or work, or deteriorating performance
intense focus on particular ideas, which may seem odd or disturbing to others
These symptoms are very general, and not necessarily a sign of psychosis. Family members should observe these changes and note if they persist.
