Obesity may not be a risk factor for idiopathic intracranial hypertension in Asians.

OBJECTIVE

Idiopathic intracranial hypertension (IIH) is a clinical condition characterized by signs and symptoms of increased intracranial pressure. We demonstrated the clinical presentation of IIH of Asians and investigated any ethnic difference in pathogenesis.

RESULTS

Ten patients who fulfilled the modified Dandy criteria and four with presumed diagnosis for IIH were included. Only one patient (7.1%) was obese according to body mass index, seven were overweight, and six weighed normal.

CONCLUSIONS

Obesity was not frequently found in Caucasians with IIH. This data indirectly suggest that obesity may not play a major role in the pathogenesis of IIH in Asians. Awareness of this is helpful in early diagnosis and treatment of IIH in Asians.
