“…However, contrary to our expectations we didn't find any association between nocturnal attacks and progesterone receptor gene polymorphism. Although a relation between nocturnal panic attacks and hypersensitivity of the brain stem chemoreceptors to CO2 was documented (31,32), our results didn't support progesterone gene polymorphysm's involvement in these mechanisms. Nevertheless our finding is in accordance with Freire et al (33) where they didn't found any correlation between the RS and nocturnal panic attacks phenomenologically.…”

“…Only one study, to our knowledge, has examined familial history in NP versus DP subgroups. O'Mahony and Ward [2003] found no between-group differences in family history of panic attacks. Overall, 77% had at least one family member with a history of panic attacks.…”

Nocturnal panic and recent life events

Recent research has hypothesized an association between traumatic events and nocturnal panic (NP). The purpose of this study was to investigate whether the onset of nocturnal panic attacks is associated with a higher frequency of and/or greater severity of stressful or traumatic life events than that of patients with panic disorders (PDs) who experience daytime panic attacks (DPs) while awake. A secondary aim was to investigate whether NP is associated with specific life events at the onset of the disorder. Our sample comprised 129 subjects with PD (DSM-IV). We investigated the number and types of stressful life events that occurred in the year prior to PD onset using a semistructured interview. Of the sample, 28.7% had recurrent nocturnal panic attacks (NP group). Subjects with and without recurrent NP did not differ on any sociodemographic or clinical characteristic. Neither the number nor type of life event distinguished those with or without NP. The subgroup of patients with PD with recurrent NP appears to represent a variant of PD with a possible increased vulnerability to conditions of diminished arousal as a trigger of panic attacks. However, the hypothesis that this vulnerability might be determined by life events that occur in the period preceding PD onset was not supported by the findings of this study.

“…Several studies found no association between presence of nocturnal panic and self-reported age of onset of panic disorder. [39,40,52] Other research reported longer mean self-reported duration of panic disorder within nocturnal and diurnal panic groups relative to diurnal-only panic groups, [6,53] although one study found no such association. [39] Also, two of the studies found no differences in self-reported stressful life events between the two groups.…”

“…The small body of research examining the relation of nocturnal panic to familial psychiatric history has found no reliable association. Three studies utilizing self-report data for patients with nocturnal and diurnal panic and patients with diurnal-only panic [40,52,53] found no group differences in history of panic disorder among first-degree relatives. However, one of the studies [52] indicated a greater prevalence of at least one Axis I disorder among first-degree relatives, not specific to panic disorder.…”

Subtypes of panic attacks: a critical review of the empirical literature

Although at present the data do not warrant the utility of subtyping, further research aimed at patent gaps in the literature, including clearer operationalization of symptom subtypes, greater use of biological challenge paradigms and physiological and other more objective measures of fear and anxiety, and exploration of subtyping based on biological factors such as genetics, may support the future designation of panic attack subtypes and their ultimate clinical utility.
