A homeopathic 'Materia medica' is a collection of "drug pictures", organised alphabetically by remedy, that describes the symptom patterns associated with individual remedies.

However, the course of RAD is not well studied and there have been few efforts to examine symptom patterns over time.

Eventually, the term Alzheimer's disease was formally adopted in medical nomenclature to describe individuals of all ages with a characteristic common symptom pattern, disease course, and neuropathology.

Its symptom pattern represents a final common pathway resulting from the interplay of three broad classes of predisposing factors shown in figure 2.

If any of the symptom pattern is present before the stressor, another diagnosis is required, such as Brief psychotic disorder or Major depressive disorder.

The symptom pattern for Acute stress disorder must occur and be resolved within four weeks of the trauma.

If it lasts longer, and the symptom pattern fits that characteristic of PTSD, the diagnosis may be changed.

The pediatric domains are classified first by age range and then by symptom pattern or area of symptom.

Classification may instead be based on broader underlying "spectra", where each spectrum links together a range of related categorical diagnoses and nonthreshold symptom patterns.

Other symptom patterns of the bubonic plague, such as septicemic plague and pneumonic plague were also present.
