It has been suggested that synesthesia develops during childhood when children are intensively engaged with abstract concepts for the first time. [12] This hypothesis—referred to as semantic vacuum hypothesis —could explain why the most common forms of synesthesia are grapheme-color, spatial sequence, and number form.
The genetic mechanism of synesthesia has long been debated, with researchers previously claiming it was a single X-linked trait due to seemingly higher prevalence in women and no evidence of male-male transmission [1] This is where the only synesthetic parent is male and the male child has synesthesia, [2] [3] meaning that the trait cannot be solely linked to the X chromosome.
While developmental synesthesia likely has a genetic origin, there are also ways to develop synesthesia. Acquired synesthesia is a form of synesthesia that can materialize later on in life, usually following a brain injury or the loss of sensory input to the central nervous system from afferent nerves, which is called sensory deafferentation.

This is a list of notable people who have claimed to have the neurological condition synesthesia.Following that, there is a list of people who are often wrongly believed to have had synesthesia because they used it as a device in their art, poetry or music (referred to as pseudo-synesthetes).
