Severity of Allergic Rhinitis
• Mild allergic rhinitis symptoms include the following:
a.Normal sleep
•Normal daily activities, sports and leisure
•Normal work and school
•No troublesome symptoms
Moderate-to severe allergic rhinitis symptoms must
include one or more of the following:
•Abnormal sleep
•Impairment of daily activities, sport and leisure
•Problems caused at work or school •Troublesome symptoms.

Cognitive function
High level functions carried out by the
human brain, including comprehension
and use of speech, visual perception and
construction, calculation ability, attention
(information processing), memory, and
executive functions such as planning,
problem-solving, and self-monitoring.

Allergic rhinitis
• Each year affect between 1.4% and 39.7%
• Peak age of onset in adolescence
• Sleep problem affects on the cognition, esp in
Perennial allergic rhinitis
• Methods to test cognitive function need training
• This talk will be focused on ≥ adolescence and
childhood with seasonal allergic rhinitis

Conclusion
• Different tools by psychiatrists, not allergists.
• Allergic rhinitis impairs the cognitive function.
• Mechanism yet determined but in part, direct influence
on CNS.
• How to minimize the impairment of cognitive function.
• Further, the research about cognitive function in
perennial AR or persistent AR.
