People with pFAS have a confirmed history of prenatal alcohol exposure, but may lack growth deficiency or the complete facial stigmata. Central nervous system damage is present at the same level as FAS. These individuals have the same functional disabilities but "look" less like FAS.The following criteria must be fully met for a diagnosis of Partial FAS:
Growth deficiency: Growth or height may range from normal to deficient
FAS facial features: Two or three FAS facial features present
Central nervous system damage: Clinically significant structural, neurological, or functional impairment in three or more of the Ten Brain Domains
Prenatal alcohol exposure: Confirmed prenatal alcohol exposure

Fetal alcohol effects
Fetal alcohol effects (FAE) is a previous term for alcohol-related neurodevelopmental disorder and alcohol-related birth defects. It was initially used in research studies to describe humans and animals in whom teratogenic effects were seen after confirmed prenatal alcohol exposure (or unknown exposure for humans), but without obvious physical anomalies. Smith (1981) described FAE as an "extremely important concept" to highlight the debilitating effects of brain damage, regardless of the growth or facial features. This term has fallen out of favor with clinicians because it was often regarded by the public as a less severe disability than FAS, when in fact its effects can be just as detrimental. Alcohol-related neurodevelopmental disorder
Alcohol-related neurodevelopmental disorder (ARND) was initially suggested by the Institute of Medicine to replace the term FAE and focus on central nervous system damage, rather than growth deficiency or FAS facial features. The Canadian guidelines also use this diagnosis and the same criteria.
The condition appears to be genetically determined and caused by the presence in the nose of erectile tissue which may become engorged during sexual arousal, as a side effect of the signals from the autonomic nervous system that trigger changes in the genitals of both men and women. A related condition called sexually induced sneezing also exists, where people sneeze, sometimes uncontrollably, when engaging in or even thinking about sexual activity. A phenomenon presumably related to honeymoon rhinitis is the frequent side effect of nasal congestion during the use of Viagra or related phosphodiesterase type 5 antagonists. Gustatory rhinitis – spicy and pungent food may in some people produce rhinorrhea, nasal stuffiness, lacrimation, sweating and flushing of face. It can be relieved by ipratropium bromide nasal spray (an anticholinergic), a few minutes before a meal. Non-air flow rhinitis – it is seen in patients of laryngectomy, tracheostomy and choanal atresia. Nose is not used for air flow and the turbinates become swollen due to loss of vasomotor control. In choanal atresia there is an additional factor of infection due to stagnation of discharge in the nasal cavity which should otherwise drain freely into nasopharynx. Photic sneeze reflex is a reflex condition that causes sneezing in response to looking at bright lights. Presentation
Paroxysmal sneezing in morning, especially in morning while getting out of bed. Excessive rhinorrhea – watering discharge from the nose when patient bends forward.
