Friedrich Nietzsche: the wandering and learned neuropath under Dionisius.

Friedrich Nietzsche (1844-1900) was a remarkable philologist-philosopher while remaining in a condition of ill-health. Issues about his wandering/disruptive behavior that might be a consequence and/or protection against his cognitive decline and multifaceted disease are presented. The life complex that raises speculations about its etiology is constituted by: insight, creativity and wandering behavior besides several symptoms and signs of disease(s), mainly neurological one. The most important issue to be considered at the moment is not the disease diagnosis (Lissauer's general paresis or CADASIL, e.g.), but the probable Nietzsche's great cognitive reserve linked to the multifactorial etiology (genetic and environmental), and shared characteristics both to creativity and psychopathology. This makes any disease seems especial regarding Nietzsche, and whichever the diagnostic hypothesis has to consider the Nietzsche's unique background to express any disease(s).

Friedrich Nietzsche and his illness: a neurophilosophical approach to introspection.

There are some arguments that Friedrich Nietzsche suffered from the autosomal dominant vascular microangiopathy: Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). Here, 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. Alterations of the brain default and reward networks would account for such an increased level of introspection and creativity. A new framework on approaching illness is proposed, which, in conformity with Nietzsche's positive view, outlines the enabling aspects of some otherwise highly disabling neuropsychiatric disorders.

The madness of Dionysus -- six hypotheses on the illness of Nietzsche.

BACKGROUND: Friedrich Nietzsche (1844-1900) is considered as one of the most influential modern thinkers of the last two centuries. The great philosopher and poet developed a mental illness at the age of 44 and died at the age of 56. Pathological examination was not undertaken. At that time Nietzsche was diagnosed as having atypical paralysis progressiva, however recently five other probable diagnoses appeared in literature. METHOD: Literature search in MEDLINE and Web of Science on the illness of Nietzsche. RESULTS: Six hypotheses were identified: 1. Paralysis progressiva (General paralysis of the insane) 2. Bipolar affective disorder followed by vascular dementia 3. Hereditary form of frontotemporal dementia 4. Brain tumor 5. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) 6. Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) syndrome. CONCLUSION: Developments in neurology and molecular genetics give new perspectives to the secret of Nietzsche's illness and also there is a consensus on the questioning of the original paralysis progressiva concept. As there was no postmortem, the clinical speculations on the medical problems of the great philosopher remain a challenge.

The neurological illness of Friedrich Nietzsche.

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 ending in a dementia with total physical dependence due to stroke. From the very beginning, Nietzsche's dementia was attributed to a neurosyphilitic infection. Recently, this tentative diagnosis has become controversial. OBJECTIVE: To use historical accounts and original materials including correspondence, biographical data and medical papers to document the clinical characteristics of Nietzsche's illness and, by using this pathography, to discuss formerly proposed diagnoses and to provide and support a new diagnostic hypothesis. MATERIALS: Original letters from Friedrich Nietzsche, descriptions by relatives and friends, and medical descriptions. Original German sources were investigated. Biographical papers published in medical journals were also consulted. RESULTS: Nietzsche suffered from migraine without aura which started in his childhood. In the second half of his life he suffered from a psychiatric illness with depression. During his last years, a progressive cognitive decline evolved and ended in a profound dementia with stroke. He died from pneumonia in 1900. The family history includes a possible vascular-related mental illness in his father who died from stroke at 36. CONCLUSIONS: Friedrich Nietzsche's disease consisted of migraine, psychiatric disturbances, cognitive decline with dementia, and stroke. Despite the prevalent opinion that neurosyphilis caused Nietzsche's illness, there is lack of evidence to support this diagnosis. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) accounts for all the signs and symptoms of Nietzsche's illness. This study adds new elements to the debate and controversy about Nietzsche's illness. We discuss former diagnoses, comment on the history of a diagnostic mistake, and integrate for the first time Nietzsche's medical problems.

John Ruskin's relapsing encephalopathy.

John Ruskin (1819-1900) is chiefly remembered for his works on painting and architecture, and for his powerful and original prose style. In middle age, he suffered recurring episodes of delirium with visual hallucinations and delusions. At about the same time, his writing developed a disjointed polemical character, with cryptic and intemperate elements that disorientated some readers. The nature of Ruskin's 'madness' is a key to understanding his later writing career but the psychiatric explanations given by many of his literary biographers seem unsatisfactory. Ruskin left numerous clues about the illness in his diaries, correspondence and publications. It is likely that he had a relapsing-progressive neurological disorder with neuropsychiatric manifestations. It could have been a fluctuating metabolic or immunological encephalopathy, but the diagnosis that best fits the time course of his illness and the prior history of mood disorder and of migraine with aura is Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). Whatever the pathology, its first effects on frontal lobe function may have actually enhanced Ruskin's creative energy for a long time before stepwise cognitive impairment degraded his ability to write.

CADASIL: a short review of the literature and a description of the first family from Greece.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited disease clinically characterized by migraine, subcortical ischemic events, dementia and mood disorders. We present a short review of the literature on the clinical presentation of patients with CADASIL and provide recommendations for the detection and diagnosis of similar cases. We also describe the clinical, radiological and genetic findings of two Greek patients with CADASIL, members of the same family.
