The illness of van Gogh has perplexed 20th-century physicians, as is evident from the nearly 30 different diagnoses that have been offered, from lead poisoning or Ménière’s disease to a wide variety of psychiatric disorders. Many writers have acknowledged the epilepsy but considered the psychiatric disorder an independent mental illness. Monroe
(7,
8) recognized the unique episodicity of van Gogh’s mental changes, the role of absinthe in his illness, and an underlying epileptoid limbic dysfunction that was associated with his creativity but also, if overly intense, would render him ill. Earlier, in an exceptionally well-documented study, Gastaut
(1) reasoned that the artist’s psychiatric changes were based on temporal lobe epilepsy produced by the use of absinthe in the presence of an early limbic lesion.
Earlier in his life, van Gogh experienced two prolonged episodes of reactive depression. Both episodes were followed by a prolonged period of hypomanic or even manic behavior: first as evangelist to the poor miners in Belgium and then as the quarrelsome and overly talkative artist in exciting Paris. The major illness of his last 2 years developed in the presence of seizures, and its nature has remained controversial. The known details of his psychiatric illness will be reviewed together with what is known about the psychopathology of individuals with epilepsy, and differential diagnostic considerations will follow.
Views of Gastaut and the Earlier French Physicians
Felix Rey, the young physician who attended van Gogh in Arles and diagnosed his epilepsy, was familiar with the psychiatric aspects of epilepsy as they were taught in France during the second half of the 19th century. In fact, Aussoleil, a medical school companion of Felix Rey, wrote a dissertation on larvate epilepsy and worked nearby when van Gogh was admitted to the hospital in Arles
(1). In 1860, Morel
(9) listed the symptoms that were to be so prominent in van Gogh’s illness:
Under the term larvate epilepsy I have described a variant of epilepsy which does not reveal itself by the actual minor or major attacks, but on the contrary by all the other symptoms which accompany or precede ordinary epilepsy characterized by seizures, that is: periodic alternation of excitement and depression; manifestations as it were of sudden fury without sufficient grounds and for most trivial reasons; a usually most irritable disposition; amnesia, as usually occurs in epilepsy, of dangerous acts carried out during momentary or transient rages. Some epileptics of this type have even experienced genuine auditory and visual hallucinations.
Morel had already recognized the highly conscientious (hypersocial) disposition of such patients that contrasted strikingly with their proneness to outbursts of violent anger.
Gastaut
(10) pointed out that premodern psychiatrists who had studied institutionalized patients with epilepsy chiefly had observed individuals with mesial temporal sclerosis, as documented by their neuropathologic studies. His findings linked premodern psychiatric views of epilepsy to modern epileptology. Gastaut published his study of van Gogh in 1956, after he had conducted a series of investigations on carefully selected groups of patients with different forms of epilepsy. He documented that certain behavioral and emotional changes among patients with epilepsy were specifically related to mesial (limbic) temporal lobe epilepsy: episodic irritability contrasting with an otherwise hypersocial disposition, slow-adhesive (viscous) personality traits, and a global hyposexuality
(11–
13). This temporal lobe syndrome associated with epilepsy was manifest in van Gogh.
Gastaut pointed out that the three major interictal behavior changes of patients with mesial temporal lobe epilepsy—heightened emotionality (with enhanced anger, moods, and fear), viscosity (adhesiveness), and hyposexuality—represent the very opposites of the Klüver-Bucy syndrome observed after bilateral temporal lobe resections in animal experiments—placidity, flighty attention span, and hypersexuality
(14,
15). He noted that this was not a surprising finding considering that interictally, because of the effects of the irritative lesion, patients with temporal lobe epilepsy present a state of excitation of the temporal limbic system as opposed to a state of depression after the ablation experiment. While viscosity and hyposexuality tend to be relatively persistent, the heightened emotionality tends to appear in a highly labile or alternating pattern.
Gastaut recognized the crucial role of absinthe in the manifestation of van Gogh’s major psychiatric symptoms. By his own confession, van Gogh required “a glass too much” to numb his inner storms when they became too intense. The artist was not known to become intoxicated and may not have been drinking more than many of his contemporaries, but he was particularly vulnerable to the epileptogenic properties of absinthe, the favorite drink of the French artists of his time. Oil of wormwood (from the herb
Artemisia absinthium) constitutes the toxic principle of the alcoholic drink absinthe. Wormwood oil contains the terpene compound thujone, a structural isomer of camphor. Both thujone and camphor induce convulsions and were used during the 1920s and 1930s in the study of models for epilepsy; von Meduna considered the use of thujone for the convulsive therapy of schizophrenia before using camphor
(16,
17). In 1873, Magnan
(18) described for the first time what he termed
épilepsie absinthique, and later neurologic textbooks of the period referred to the relationship of absinthe and epilepsy. In the early part of the 20th century, absinthe became outlawed in most countries because of its psychotoxic effects.
During his stay in Paris, where he was introduced to absinthe, van Gogh developed complex partial seizures with gradual accentuation of partially preexisting emotional and behavioral changes. In most patients with temporal lobe epilepsy, psychiatric changes tend to occur only gradually and in a less violent form. In van Gogh, perhaps because of an early temporal-limbic lesion, these changes became fully evident soon, characterized by heightened emotionality with the opposite poles of irritability and hyperethical or hyperreligious trends, by meticulous attention to detail and stubborn persistence in speech and writing (viscosity), and by hyposexuality
(11–
13). His seizures and his psychotic episodes were precipitated by the use of absinthe and stopped once he abstained.
Modern Concepts of the Neuropsychiatric Disorders of Epilepsy
The presence of seizures, the intermittent and pleomorphic symptoms of the interictal phase, the prolonged amnestic-confusional psychotic episodes at the height of van Gogh’s illness, and, finally, the profile of his personality traits all suggest a diagnosis of epilepsy-related illness.
While in Arles, van Gogh developed an interictal dysphoric disorder with the near complete range of its intermittent and pleomorphic (affective-somatoform) symptoms: irritability, depressive and euphoric moods, anxiety, anergia, insomnia, and pains. The artist probably also had a fear of heights, but phobic symptoms cannot be considered a well-established symptom of dysphoric disorder. Interictal dysphoric disorder was well recognized by premodern psychiatrists from the German language area as the most common psychiatric disorder (
Verstimmungszustand) associated with epilepsy
(19,
20). The validity and the importance of this diagnostic concept have been affirmed
(21–
24). At least three of its seven symptoms need to be present, each to a troublesome degree, to meet the diagnostic criteria for interictal dysphoric disorder. In his letters, van Gogh referred to his dysphoric symptoms as “attacks of melancholy,” “moments of enthusiasm or madness,” “fits of anxiety,” or a transient “feeling of emptiness and fatigue,” rendering a lucid picture of highly episodic mental states that clearly are more intermittent and pleomorphic than those experienced by an individual with the more sustained mood changes of manic-depressive illness. He also reported insomnia and stomach pains but was not outspoken about his frightening outbursts of rage, which were well documented by Gauguin and many others. While his stomach pains are of uncertain origin, van Gogh clearly reported six of the seven cardinal symptoms of interictal dysphoric disorder.
Interictal dysphoric disorder, not recognized in its entirety by Gastaut, represents a refinement of the description by early French psychiatrists that included only the most striking features of the disorder: periodic alternation of excitement and depression and episodes of fury
(9). The validity of interictal dysphoric disorder as a diagnostic entity is confirmed by its specific etiology, phenomenology, course, and its response to specific psychotropic medication
(24,
25). The disorder tends to appear interictally during predominance of seizure-suppressing inhibitory mechanisms. This phenomenon was termed “forced normalization” by Landolt, who observed that dysphoric moods, as well as psychotic episodes, tend to be associated with EEG normalization
(26,
27). Dysphoric symptoms also tend to be present in the prodromal and particularly in the postictal phase, when they seem to result from the acute engagement of inhibitory responses at the time of seizure events. It is assumed that still poorly defined inhibitory mechanisms exert psychotoxic effects in both the interictal and the peri-ictal phases of epilepsy
(23,
24).
Severe dysphoric disorders may become readily associated with psychotic symptoms
(19,
20,
28). At the height of his illness, van Gogh became hallucinatory, paranoid, and delusional with confusional-amnestic features, all known to occur in psychosis due to epilepsy. Psychosis due to epilepsy may follow a flurry of seizures (i.e., postictal psychosis), appearing often but not invariably with amnestic-confusional features. Alternatively, the psychosis may occur during the interictal phase, in the absence of clouded consciousness, particularly when seizure activity has become suppressed. In both instances, psychosis, like the dysphoric symptoms, seems to result from excessive inhibitory activity that has become either acutely engaged in the postictal phase by the preceding seizure activity or predominant in the interictal phase. A third type of epilepsy-associated psychosis, termed para-ictal psychosis
(29), occurs with ongoing frequent seizure activity and combines features of both the postictal and the interictal psychoses; this type of psychosis is now rare because of the advent of effective antiepileptic medication. The psychotic symptoms seen in van Gogh apparently were precipitated by the epileptogenic absinthe, but no modern experience with this substance exists. From what is known, his psychotic episodes neither followed a flurry of seizures nor occurred at times when his seizures had diminished, and his prolonged psychotic episodes may be best classified as para-ictal. While interictal psychoses require psychotropic medication, para-ictal psychoses respond to improved antiepileptic medication
(28), and van Gogh was probably correct when he recognized a beneficial effect on his psychosis from Dr. Rey’s prescription of potassium bromide. Recurrences followed the initial episode, when he relapsed into using absinthe, and were perhaps more prolonged when he was not treated with potassium bromide during his year in the asylum.
There has been fair agreement among experts about the personality traits observable among patients with epilepsy
(19,
20,
30–33). Vincent’s viscosity was manifest by his intense clinging to people he loved, his persevering on details, and a tendency to debate endlessly and to write excessively. Gastaut viewed viscosity as the characteristic core trait of an individual with temporal lobe epilepsy
(11,
13). Gastaut also pointed out how van Gogh’s hypersocial, spiritual, and even hyperreligious personality contrasted sharply with his episodes of anger to the point of fury
(1), a conflict that other authors have considered the dynamic core issue in patients with epilepsy and heightened emotionality
(34).
Before becoming an artist, van Gogh had been devoted to a religious career for years and had served as an utterly selfless evangelist; religious motives later reemerged in his artwork. Yet his episodic rages are well documented, became notorious once he used absinthe, and reached a peak with his acute illness and the murderous gesture directed at Gauguin. He represents an example of the heightened conflict between fury and atonement—good and evil forces—that has so often been noted among individuals afflicted with epilepsy. Paroxysmal episodes of irritability to the point of rage on the one hand and a (remorseful) highly ethical, selfless, helpful, and often hyperreligious disposition on the other had been noted by observers before Gastaut, from Morel and Kraepelin to Freud and Szondi.
In his essay “Dostoevsky and Parricide,” Freud
(35) rendered a coherent picture of the contradictory personality of this great author who had epilepsy. Elements seen in Dostoevsky’s life and novels included experiencing the threat of repeated uncontrollable acts of violence, feeling guilt and the need for atonement, seeking forgiveness and help from God, attempting to adhere to a strict moral code, and proving oneself to be the mildest, kindest, most helpful person possible. In Szondi’s genetically based system of human drives
(24,
34,
36), the tendency to accumulate and discharge crude affects (anger, hate, vengeance, envy, or jealousy) is paired with the opposite tendency to make amends (repentance, tolerance, kindness, helpfulness, or piety). These two tendencies determine ethical behavior and appear most pronounced in epilepsy.
Suicidal attempts infrequently may be carried out in a state of acute postictal depression
(37,
38). The artist’s earlier suicide attempts probably had been of this nature and were not consciously planned. In patients with interictal dysphoric disorder, the moods of euphoria tend to be brief, their depressive moods more prominent. With the latter comes a suicidal risk that is 4–25-fold higher among patients with epilepsy over the rate in the general population and is particularly associated with chronic temporal lobe epilepsy
(39). Suicide tends to occur, peculiarly, at a time when a long-standing seizure disorder has been brought into remission and often comes as a surprise
(37,
40).
Supported by his brother Theo, van Gogh had lived for his art. Theo was the one person in his life who had faith in Vincent’s extraordinary accomplishments and had been, in fact, the lifeline throughout his career as an artist. With Theo’s support threatened, the storm within became less bearable. When considering the forward-looking tone of his last letter to Theo, Hulsker had no doubt that the suicidal act resulted from a momentary impulse
(3). For the last few months of his life, van Gogh had abstained from absinthe and was free from both seizures and psychosis. Depressive moods were more prevalent, although not persistent. His productivity had been unbroken in Auvers, and his suicide was not anticipated by those who knew him. It seems to have occurred with a final attack of melancholy, resulting from a still persistent dysphoric disorder. One needs to remember, however, that van Gogh had experienced marked depressive episodes before his seizure disorder.
Differential Diagnostic Considerations
Several authors have offered a tentative diagnosis of schizophrenia for van Gogh. In view of both the absence of any of the fundamental symptoms of the disorder and the presence of psychotic episodes with amnestic-confusional features and complete recovery, this diagnosis appears improbable, in spite of the fact that late-onset schizophrenia was diagnosed in one of his sisters.
The diagnosis of neurosyphilis has to be considered in view of van Gogh’s lifestyle (he was treated for gonorrhea in 1882), the prevalence of the disease at the time, and its diverse symptoms. However, none of the relatively specific symptoms of the disease was ever noted. Above all, this diagnosis is unlikely, since he did not show any persistent impairment of mental or somatic functions.
Following two major disappointments (an unrequited early love and a failed career as an evangelist), van Gogh clearly experienced prolonged episodes of depression; both events preceded major career changes. He also experienced sustained periods of hypomania or mania. His career as an evangelist ended when he developed a sort of altruistic religious mania. A bipolar history of prolonged periods of extremely high levels of energy, enthusiasm, and productivity alternating with episodes of depression is not uncommon among writers and artists, and the hypomanic phase is often not identified
(41). The artist’s increasingly elevated mood during his exciting stay in Paris probably was a factor in his use of absinthe, the substance that precipitated his second major illness.
Vincent experienced seizures only after his use of absinthe with its convulsant property. He never experienced generalized seizures but had only partial seizures, suggesting the presence of a latent epileptogenic zone, most likely in the mesial-temporal area, that was activated by his use of absinthe. As postulated by Gastaut, a perinatal brain lesion may have resulted in van Gogh’s severe reaction to absinthe: the partial seizures, the marked interictal dysphoric disorder, and the psychotic episodes with prominent amnesia. When he became increasingly ill during the last 2 years of his life, van Gogh did not experience any of the sustained mood changes characteristic of bipolar disorder. Instead, he experienced sudden and brief changes of depressive mood, elation, anxiety, or fury, and his intense artistic efforts were frequently disrupted by episodes of listlessness; these intermittent pleomorphic changes developed after onset of seizures and are specific for the dysphoric disorder of epilepsy.
While interictal dysphoric disorder and psychosis tend to become manifest after an interval of years following onset of epilepsy, there are also patients with dysphoric or epileptoid traits in the absence of overt seizures; these patients often have identifiable subtle brain lesions
(24,
42). The existence of an epileptoid temperament analogous to schizoid or cyclothymic temperaments, before or independent of the respective major illness, was often debated in the premodern psychiatric literature when epilepsy was a major topic
(20). The early intense emotionality of van Gogh, with the contrasting poles of explosive irritability on the one hand and goodness and religiosity on the other, may be considered an expression of this temperament independent from his cyclothymic disposition.
Vincent van Gogh’s suicide may have been an unexpected event, perhaps precipitated by a dysphoric mood; remission of the seizures may have favored the final depressive event. But when he had recovered from his severe illness upon discharge from the asylum, the support from his brother, upon whom he had depended totally for his career as an artist, had become seriously threatened. Although the artist had been able to remain productive, a depressive mood had become more evident. In the past, he had reacted to crucial losses with marked depression, and this illness probably was the main factor in his death.
