^ The pronunciation of "Van Gogh" varies in both English and Dutch. Especially in British English it is /ˌvæn ˈɡɒx/[2] or sometimes /ˌvæn ˈɡɒf/.[3] American dictionaries list /ˌvæn ˈɡoʊ/, with a silent gh, as the most common pronunciation.[4] In the dialect of Holland, it is [ˈvɪnsɛnt fɑŋˈxɔx] (listen), with a voiceless V. He grew up in Brabant, and used Brabant dialect in his writing; if he pronounced his name with a Brabant accent it would be [vɑɲˈʝɔç], with a voiced V and palatalised G and gh. In France, where much of his work was produced, it is [vɑ̃ ɡɔɡᶱ].[5]
There have been numerous debates as to the nature of Van Gogh's illness and its effect on his work, and many retrospective diagnoses have been proposed. The consensus is that Van Gogh had an episodic condition with periods of normal functioning.[195] Perry was the first to suggest bipolar disorder in 1947,[196] and this has been supported by the psychiatrists Hemphill and Blumer.[197][198] Biochemist Wilfred Arnold has countered that the symptoms are more consistent with acute intermittent porphyria, noting that the popular link between bipolar disorder and creativity might be spurious.[195] Temporal lobe epilepsy with bouts of depression has also been suggested.[198] Whatever the diagnosis, his condition was likely worsened by malnutrition, overwork, insomnia and alcohol.[198] 

Van Gogh had many influences on his life including his family and friends, other artists such as Paul Gauguin, and his failing mental and physical health.

Van Gogh had no recollection of the event, suggesting that he may have suffered an acute mental breakdown.[147] The hospital diagnosis was "acute mania with generalised delirium",[148] and within a few days the local police ordered that he be placed in hospital care.[149][150] Gauguin immediately notified Theo, who on 24 December had proposed marriage to his old friend Andries Bonger's sister Johanna.[151] That evening Theo rushed to the station to board a night train to Arles. He arrived on Christmas Day and comforted Vincent, who seemed to be semi-lucid. That evening he left Arles for the return trip to Paris.[152]

In April 2013, Van Dyke revealed that for seven years he had been experiencing symptoms of a neurological disorder, in which he felt a pounding in his head whenever he lay down; but despite his undergoing tests, no diagnosis had been made.[55] He had to cancel scheduled appearances due to fatigue from lack of sleep because of the medical condition.[56] In May 2013, he tweeted that it seemed his titanium dental implants may be responsible.[57]
Van Gogh's mother came from a prosperous family in The Hague,[19] and his father was the youngest son of a minister.[20] The two met when Anna's younger sister, Cornelia, married Theodorus's older brother Vincent (Cent). Van Gogh's parents married in May 1851 and moved to Zundert.[21] His brother Theo was born on 1 May 1857. There was another brother, Cor, and three sisters: Elisabeth, Anna, and Willemina (known as "Wil"). In later life Van Gogh remained in touch only with Willemina and Theo.[22] Van Gogh's mother was a rigid and religious woman who emphasised the importance of family to the point of claustrophobia for those around her.[23] Theodorus's salary was modest, but the Church supplied the family with a house, a maid, two cooks, a gardener, a carriage and horse, and Anna instilled in the children a duty to uphold the family's high social position.[24]
Theo died in January 1891, removing Vincent's most vocal and well-connected champion.[267] Theo's widow Johanna van Gogh-Bonger was a Dutchwoman in her twenties who had not known either her husband or her brother-in law very long and who suddenly had to take care of several hundreds of paintings, letters and drawings, as well as her infant son, Vincent Willem van Gogh.[262][note 14] Gauguin was not inclined to offer assistance in promoting Van Gogh's reputation, and Johanna's brother Andries Bonger also seemed lukewarm about his work.[262] Aurier, one of Van Gogh's earliest supporters among the critics, died of typhoid fever in 1892 at the age of twenty-seven.[269]
Limited access to life outside the clinic resulted in a shortage of subject matter. Van Gogh instead worked on interpretations of other artist's paintings, such as Millet's The Sower and Noonday Rest, and variations on his own earlier work. Van Gogh was an admirer of the Realism of Jules Breton, Gustave Courbet and Millet,[164] and he compared his copies to a musician's interpreting Beethoven.[165]
The police found van Gogh in his room the next morning, and admitted him to the Hôtel-Dieu hospital. Theo arrived on Christmas Day to see van Gogh, who was weak from blood loss and having violent seizures. The doctors assured Theo that his brother would live and would be taken good care of, and on January 7, 1889, van Gogh was released from the hospital. 

What particularly struck me when I saw the old Dutch paintings again is that they were usually painted quickly. That these great masters like Hals, Rembrandt, Ruisdael – so many others – as far as possible just put it straight down – and didn't come back to it so very much. And – this, too, please – that if it worked, they left it alone. Above all I admired hands by Rembrandt and Hals – hands that lived, but were not finished in the sense that people want to enforce nowadays ... In the winter I'm going to explore various things regarding manner that I noticed in the old paintings. I saw a great deal that I needed. But this above all things – what they call – dashing off – you see that's what the old Dutch painters did famously. That – dashing off – with a few brushstrokes, they won't hear of it now  – but how true the results are.
In 1892 Émile Bernard organised a small solo show of Van Gogh's paintings in Paris, and Julien Tanguy exhibited his Van Gogh paintings with several consigned from Johanna van Gogh-Bonger. In April 1894 the Durand-Rue Gallery in Paris agreed to take 10 paintings on consignment from Van Gogh's estate.[269] In 1896, the Fauvist painter Henri Matisse, then an unknown art student, visited John Peter Russell on Belle Île off Brittany.[270][271] Russell had been a close friend of Van Gogh; he introduced Matisse to the Dutchman's work, and gave him a Van Gogh drawing. Influenced by Van Gogh, Matisse abandoned his earth-coloured palette for bright colours.[271][272]
