Tiredness, exhaustion, muscular pain, listlessness, shortness of breath with exertion, profuse sweating, morning stiffness, joint pains, concentration disorder, forgetfulness, depressive moods, aggressive behaviour, anxieties, visual disturbance, dizziness, sleeping disorder Toxoplasma gondii is a tiny parasite which infects 30 - 50% of the world's population. The symptoms listed above can result if it becomes chronically active – an alarming disease which affects far more people than has been historically assumed. In Germany about 800.000 patients could be affected, and it can be assumed that there are many more worldwide. Toxoplasma gondii is equipped with outstanding camouflage abilities, and often cannot be detected by our standard lab tests, and therefore the prevalence of Toxoplasma related diseases is vastly underestimated by medicine. The result is that many patients who suffer from this disease do not have a chronic active toxoplasmosis considered by their physician. Often these patients receive treatment for a supposed psychosomatic disorder, fibromyalgia, chronic fatigue, seronegative rheumatoid arthritis and many more rather than the treatment they need for their very real problem. This book shows, based on basic research and in a comprehensible and comprehensive way, how chronic active toxoplasmosis can be diagnosed and how health can readily be restored by the appropriate therapy. Many patients could have a significant benefit from this, if only medicine could free itself from the incorrect and outdated idea that Toxoplasma were harmless and that its activity could be diagnosed easily and securely by standard lab procedures.
