Jessica O'ConnorAnalysis by law firm Irwin Mitchell revealed a significant increase in employment tribunal decisions involving neurodiverse conditions, with ADHD-related claims seeing an 8.5-fold rise since 2020.
The figures, drawn from the latest data published by the Ministry of Justice, show that the number of tribunal decisions citing ADHD rose from just six in the first half of 2020 to 51 in the first half of 2025 – a 750% increase.
Autism-related decisions nearly doubled, rising from 27 to 53 cases – a 96.3% increase, while dyslexia cases rose by 78.4%, from 37 to 66.
In addition, OCD-related decisions doubled from four to eight and dyspraxia saw a 175% increase, from four to 11 cases.
Tourette Syndrome remained consistently high, with 56 decisions in H1 2025, up from 48 in H1 2020.
While some conditions such as Dyscalculia and Dysgraphia remain less frequently cited, the overall trend points to a growing awareness and willingness among employees to challenge workplace discrimination related to neurodiversity.
Jenny Arrowsmith, a partner in Irwin Mitchell’s Employment Team, said: “This data underscores the importance of inclusive workplace practices and the legal risks employers face if they fail to make reasonable adjustments to enable neurodiverse employees to thrive at work.
“We’re seeing a clear upward trend in claims, particularly around ADHD and autism, which reflects both increased diagnosis and greater employee confidence in asserting their rights.
“Linked to this, before matters get to employment tribunal, we’re seeing more issues arising in which an individual’s behaviour is a factor in what’s happened, why and what response the employer should take.”
