Many scholars have argued that Nietzsche's dementia was caused by syphilis. A careful review of the evidence suggests that this consensus is probably incorrect. The syphilis hypothesis is not compatible with most of the evidence available. Other hypotheses — such as slowly growing right-sided retro-orbital meningioma — provide a more plausible fit to the evidence.

Taking into account recently described diseases, selectively collected evidence lend some support to alternative hypotheses: basal forebrain meningioma, CADASIL, MELAS and frontotemporal dementia.

The neurological illness of Friedrich

F Friedrich Nietzsche’s disease consisted of migraine, psychiatric disturbances, cognitive decline with dementia, and stroke, and Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) accounts for all the signs and symptoms of Nietzsche's illness.

BACKGROUND Friedrich Nietzsche (1844-1900), one of the most profound and influential modern philosophers, suffered since his very childhood from severe migraine. At 44 he had a mental breakdown

It is suggested that Friedrich Nietzsche suffered from mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes syndrome, which is similar to syphilis.

THE MADNESS OF DIONYSUS: A NEUROSURGICAL PERSPECTIVE ON FRIEDRICH NIETZSCHE

A close examination of Nietzsche's symptomatic progression and neurological signs reveals a clinical course consistent with a large, slow growing, right-sided cranial base lesion, such as a medial sphenoid wing meningioma.

The pathophysiology of CADASIL: studies in a Scottish cohort

Vasoreactivity was associated with the number of lacunes and brain atrophy, as were carotid intima-media thickness, vessel stiffness, and age, and this suggests vasoreactivity may have potential as a therapeutic target, or a biomarker, in CADASIL patients.

Friedrich Nietzsche and his Illness: A Neurophilosophical Approach to Introspection

A hypothesis is formulated supporting that CADASIL presenting with symptoms of bipolar disorder and Gastaut-Geschwind syndrome would contribute to the increased insight and creativity of a philosopher whose perceptions and intuitions often bear out the results of modern neuroscience.

The historical, social and cultural aspects of the interaction of syphilis and psychiatry are investigated, finding that it was not until the middle of the 20th century that it ceased to play a part in the daily life of doctors in psychiatric wards.

Nietzschean Health and the Inherent Pathology of Christianity

This paper argues that Nietzsche offers a tolerably clear conception of philosophical health, and one that is meant to be objective, though dependent upon some empirical hypotheses. The paper also
