  • One-third of respondents with psoriasis and 40% of those with AD reported greater than 10 episodes of itch per day
  • This study describes similarities and differences in the phenotype of itch, a common symptom experienced by patients with AD and psoriasis
  • Sweating was more aggravating to patients with AD, which may be related to the presence of autonomic over-reactivity in this condition
