Hypermerimna
Hypermerimna (/ˌhaɪpərmərimnə/; 'hyper' from Greek ὑπέρ (huper, “over”), '-merimna' from Greek μέριμνα (anxiety)) is an inability to remove focus from anxiety-producing stimuli, which may be caused by damage to the attention control centers of the brain.
Causes
Hypermerimna is observed when a subject with anxiety has difficulty in disengaging from novel stimuli, and may be caused by damage to the brain`s pre-frontal control regions .[1][2][3][4] The patterns of disrupted attentional control relate to findings of disrupted performance on executive functions tasks such as working memory across a wide number of different disorder groups.[5]
Treatment
Hypermerimna may respond to standard treatment for painful conditions if the anxiety is induced by pain, using various drugs such as SSRI or tricyclic antidepressants.[6]
