Background: ADHD and autism are two of the most common disabilities in the neuropsychiatric spectra. The symptoms of ADHD and autism are different based on gender and women belong to a risk group that have an increased risk of getting misdiagnosed. The consequences of a missed or delayed diagnosis causes suffering for both the individual and society. Aim: To explore women’s experiences of getting diagnosed with ADHD or autism as adults. Method: Literature study with a systematic approach. Based on the Tidal model, a qualitative content analysis with a deductive approach according to Elo and Kyngäs has been used. Results: The results are presented using three predetermined main categories, whilst the subcategories are based on an inductive approach. The results showed that the women’s experiences of receiving a diagnosis in adulthood mostly included positive feelings such as feeling of belonging, acceptance and increased self-esteem. However negative feelings such as doubt about the identity, stigmatization and mistrust towards the healthcare system emerged.  Conclusion: A diagnosis in adulthood causes mixed feelings and a need for support from the healthcare system. Lack of support leads to worsening of the mental health.
