Annoyingly, the underlying cause of writer’s cramp isn’t known.
However, it may be genetic because up to 20 percent of those affected have an affected family member.
Dr Lee added: “Studies have shown writer’s cramp in writers is more common in those with a college degree, and is also more likely in those who spend a lot of time writing every day.
“The onset typically occurs a year or so after a sudden increase in the amount of writing.
“MRI studies suggest sufferers may have developed an abnormality of their inhibitory control – the mechanism allowing an individual to complete a task in a controlled fashion.
“Dopamine transmission has also been noted to be disrupted, within the basal ganglia.”
