Drug-Induced Headache: Causes

Pathogenesis (disease development)

In principle, any drug used to treat headache can also induce headache. Neurobiological processes of pain processing and psychological factors seem to play a role. A genetic predisposition seems to be a prerequisite for the development of drug-induced headache. The identified genes are involved in different processes such as development of dependence, serotonergic and dopaminergic transmission, oxidative stress, and CGRP-dependent processes (Calcitonin Gene-Related Peptide).

Etiology (Causes)

Biographic Causes

  • Genetic burden (to date, 33 genes have been identified that increase the risk for drug-induced headache)
  • Socioeconomic factors – low social status.

Behavioral causes

Disease-related causes

Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).

  • Chronic gastrointestinal symptoms, unspecified.

Musculoskeletal system and connective tissue (M00-M99).

  • Chronic musculoskeletal complaints, unspecified.

Psyche – nervous system (F00-F99; G00-G99).

  • Depression

Other causes

  • HADS score (Hospital Anxiety and Depression Scale; used to screen for mental impairment) > 10.
