Eaton WW, et al. Lancet Psychiatry 2018 - Review. PMID 30060873
Although specific phobias often begin in childhood, their incidence peaks during midlife and old age. Phobias persist for several years or even decades in 10-30% of cases, and are strongly predictive of onset of other anxiety, mood, and substance-use disorders. ...This Review discusses the literature regarding the prevalence, incidence, course, risk factors, and treatment of specific phobias, and presents epidemiological data from several population-based surveys....

Timing of puberty in boys and girls: A population-based study
Brix N, et al. Paediatr Perinat Epidemiol 2019. PMID 30307620 Free PMC article.
This late start of follow-up limits the estimation of age at onset of puberty but not later pubertal milestones. We estimated mean age at attaining the following pubertal milestones in years with 95% confidence intervals (CI): age at menarche, voice break, first ejaculation of semen and Tanner stages for pubic hair development and breast development or genital development. ...CONCLUSION: These data indicate that age at menarche has declined and to some extent support a decline in age at attaining other markers of pubertal development among boys....

OBJECTIVE: To examine sex and age distributions in neuroleptic malignant syndrome (NMS) patients based on a systematic literature review. ...NMS incidence peaked at age 20-25 years and declined steadily thereafter, with males consistently outnumbering females at all but the oldest age intervals. ...

Age-related infertility and unexplained infertility: an intricate clinical dilemma.
Somigliana E, et al. Hum Reprod 2016 - Review. PMID 27060173
As a consequence, unexplained infertility includes several heterogeneous conditions, one being women with age-related infertility. ...Women with age-related infertility may have a different prognosis and may benefit from different treatments. Unfortunately, since fecundity declines with age, discerning between unexplained infertility and age-related infertility becomes more and more difficult as the woman's age increases. ...

Gender and obstetric factors in the determination of the age of onset of schizophrenia in a Nigerian cohort.
Afe T, et al. J Abnorm Psychol 2019. PMID 30762377
The importance of gender and obstetric factors as predictors of the age of onset of schizophrenia is debatable. Unfortunately, there is a significant dearth of studies in developing countries such as Nigeria. ...Gender and marital status were the only variables significantly related to the age of onset (p = .00). Our model predicted 10.1% of the variability in the determination of the age of onset of schizophrenia. ...

Cluster headache in relation to different age groups.
Manzoni GC, et al. Neurol Sci 2019 - Review. PMID 30796624
However, recent studies carried out in large case series of patients with CH show that not infrequently it may set in also after age 50; by contrast, onset before adolescence is very rare. ...This particular pattern of the gender ratio in relation to onset in different age groups suggests that hormonal factors may actually play a role in the genesis of CH. ...
