Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study IS to

* explore the underlying pathophysiology of chronic fatigue syndrome (CFS) in adolescents, particularly focusing on genetics, infections/immunology, endocrinology, autonomic control and cognitions
* to assess the effect of clonidine (a drug that attenuates sympathetic nervous activity) in adolescent CFS.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Persisting or constantly relapsing fatigue lasting 3 months or more.
* Functional disability resulting from fatigue to a degree that prevent normal school attendance

Exclusion Criteria

* Another disease process or current demanding life event that might explain the fatigue
* Another chronic disease (in particular pheochromocytoma, polyneuropathy, Renal insufficiency)
* Permanent use of pharmaceuticals (including hormone drugs)
* Permanently bed-ridden
* Positive pregnancy test
* Evidence of reduced cerebral and/or peripheral circulation due to vessel disease
* Know hypersensitivity towards clonidine or inert substances (lactose, sakkarose) in capsula
* Abnormal ECG (in particular bradyarrythmias due to sick sinus syndrome or AV-block. Isolated ectopic beats do not lead to exclusion)
* Supine heart rate \< 50 beats/min
* Supine systolic blood pressure \< 85 mmHg
* Systolic blood pressure fall upon standing \> 30 mmHg
