This study is a monocentric uncontrolled observational study to evaluate a 12-14 day inpatient stay in an internal medicine clinic for integrative and complementary medicine for patients with episodic migraine and/or episodic tension headache. The aim is to investigate the extent to which a 14-day inpatient stay can influence a reduction in headache days and/or pain intensity, medication use, quality of life, anxiety, depression, perceived stress, general well-being, and a reduction in sick days/work absenteeism, and prevent the chronification of migraine and may counteract the chronification of migraine or tension-type headache. In addition, patients' previous experiences with complementary naturopathic therapies, expectations and perceived benefits in everyday life will be analysed.

Primary headache disorders are among the most common neurological disorders worldwide, with a lifetime prevalence of over 90%. Tension-type headache (TTH) is the most common type of primary headache. It manifests as a dull, pressing, tightening pain that usually 'rises' from the neck to the back of the head and down to the temples on both sides, but can theoretically occur in any part of the head. The frequency of pain attacks is used to define episodic (< 15 days/month or < 180 days/year) and chronic TTH (> 15 days/month for > 3 months or > 180 days/year). The main therapeutic options are classical analgesics (non-steroidal anti-inflammatory drugs, NSAIDs; Novalgin) in acute cases or tricyclic antidepressants as prevention. Prophylaxis can be combined with (endurance) exercise or acupuncture. Migraine is rarer than TTH, affecting about 9% of the population, but it is one of the most common causes of disability worldwide. It is defined as a headache with or without preceding neurological symptoms (called an aura) and occurs mainly in middle age, between 20 and 50 years. In acute attacks, migraine headaches are treated with medication (usually classic analgesics such as NSAIDs, Novalgin or migraine-specific triptans). In cases of severe distress due to frequent and severe attacks, medication may also be used as a prophylactic measure. A distinction is also made between episodic migraine (< 15 days in the last 3 months) and chronic migraine (> 15 days/month in the last 3 months). In addition to drug therapy there are also non-drug approaches such as acupuncture, behavioural therapy, biofeedback or relaxation techniques, which may be combined with drug prophylaxis. Complications of migraine include status migraenosus (migraine attacks lasting more than 72 hours), migraine stroke and/or chronicisation of migraine. The headache disorders listed above can occur alone or in combination. When they occur together, they can severely restrict a person's daily life. According to the German Society of Neurology (DGN-Deutsche Gesellschaft für Neurologie), multimodal approaches, such as inpatient multimodal pain therapy, are explicitly recommended only in the context of chronic headache, especially chronic migraine. In addition, there are often life-limiting comorbidities, which often worsen with chronicity. The Clinic for Integrative and Complementary Medicine at the Evangelische Kliniken Essen-Mitte has been treating patients with various pain disorders for more than 20 years. Within the framework of so-called integrative care concepts with the Techniker Krankenkasse (TK) and the Barmer Ersatzkasse (BEK), headache patients are treated with naturopathic-integrative methods both as inpatients and as outpatients. The aim of this prospective observational study is to evaluate the integrative-complementary concept in patients with episodic headache (migraine and/or tension headache) without medication abuse or medication-induced headache. It will be observed whether this concept can reduce sick days/work absences, pain intensity and frequency, and medication use, thus preventing chronicity.

Inclusion Criteria:

• Acute severe mental illness (e.g. severe depression with suicidal tendencies)
• Acute, severe physical illness that prevents participation in the inpatient naturopathic programme or emergency inpatient treatment of a different kind (e.g. ongoing treatment of a cancer severe acute illness of the cardiovascular system such as heart attack, stroke, acute insufficiency of other organs (kidney, liver, etc.), other severe acute neurological diseases, e.g. relapse of multiple sclerosis, uncontrolled epilepsy)
