The presence of trichodynia in patients with telogen effluvium and androgenetic alopecia.
BACKGROUND
Trichodynia refers to pain, discomfort, and/or paresthesia in the skin of the scalp or the hair. There may be an associated psychologic comorbidity. Although androgenetic alopecia (AGA) and telogen effluvium (TE) are different entities in terms of pathogenesis, etiology, and clinical picture, both may be influenced by psychologic stress and may be the cause of secondary stress.


OBJECTIVE
To investigate the presence of trichodynia in patients with TE and AGA and to evaluate psychologic comorbidity in patients with trichodynia.


METHODS
A total of 248 patients (153 females, 95 males), presenting with hair loss due to either TE or AGA, were enrolled in this study. The prevalence of trichodynia in these two groups was compared with that in controls (n = 184). In addition, psychiatric evaluation was performed in 25 patients with trichodynia (13 females, 12 males) and in 25 controls (16 females, nine males) without alopecia and trichodynia by a psychiatrist; Diagnostic and Statistical Manual of Mental Disorders (DSM)IV criteria were used for the assessment.


RESULTS
Trichodynia was found in 72 patients (29%) with hair loss and in six controls (3.3%; P < 0.0001); 25 of the 72 patients with trichodynia underwent psychiatric evaluation and 19 of the 25 patients were found to have psychopathologic signs (76%). In the control group, only five patients had psychopathologic signs (20%; P = 0.0004). Of those with hair loss, trichodynia was more frequent in the TE group than in the AGA group (P < 0.0071).


CONCLUSIONS
Trichodynia is a common symptom in patients with TE and AGA, and often coexists with psychopathologic findings, including depression, obsessive personality disorder, and anxiety.
