Epidemiology
Eosinophilic folliculitis associated with HIV infection typically affects individuals with advanced HIV and low T helper cell counts. It affects both men and women as well as children with HIV and is found throughout the world. EF may also affect individuals with hematologic disease such as leukemia and lymphoma. It may also affect otherwise normal infants in a self-limited form. HIV-negative individuals can also develop EF — this is more common in Japan. See also

Symptoms shown to be common include:

This syndrome is characterized by incomplete penetrance. Therefore, there is a marked variability in clinical expression between the different patients. This often makes early diagnosis difficult. Cognitive impairments
Children with DiGeorge syndrome have a specific profile in neuropsychological tests. They usually have a below-borderline normal IQ, with most individuals having higher scores in the verbal than the nonverbal domains. Some are able to attend main-stream  schools, while others are home-schooled or in special classes. The severity of hypocalcemia early in childhood is associated with autism-like behavioral difficulties.Adults with DiGeorge syndrome are a specifically high-risk group for developing schizophrenia. About 30% have at least one episode of psychosis and about a quarter develop schizophrenia by adulthood.Individuals with DiGeorge syndrome also have a higher risk of developing early onset Parkinsons disease (PD). Diagnosis of Parkinsons can be delayed by up to 10 years due to the use of antipsychotics, which can cause parkinsonian symptoms. Speech and language
Current research demonstrates a unique profile of speech and language impairments is associated with 22q11.2DS. Children often perform lower on speech and language evaluations in comparison to their nonverbal IQ scores. Common problems include hypernasality, language delays, and speech sound errors.Hypernasality occurs when air escapes through the nose during the production of oral speech sounds, resulting in reduced intelligibility. This is a common characteristic in the speech and language profile because 69% of children have palatal abnormalities.
