Prognosis
Failure to manage the alcohol withdrawal syndrome appropriately can lead to permanent brain damage or death. It has been proposed that brain damage due to alcohol withdrawal may be prevented by the administration of NMDA antagonists, calcium antagonists, and glucocorticoid antagonists. Substances impairing recovery
Continued use of benzodiazepines may impair recovery from psychomotor and cognitive impairments from alcohol. Cigarette smoking may slow down or interfere with recovery of brain pathways in recovering alcoholics. References

On average, symptoms begin 3-4 hours after consumption, but can begin anywhere from several minutes to 18 hours afterward. Symptoms typically include neurologic and gastrointestinal issues including:
nauseavomiting
diarrhea
numbness and tingling in the lips, mouth, face, and extremitiesThe latter has been described as “nerves being on fire” or “ants crawling and biting all over”.Other less common symptoms can include:
ataxia
loss of coordination
limb paralysis
reversal of hot and cold sensations
slurred speech
headache
pupil dilation
generalized fatiguePatients may be thought to be disoriented or intoxicated. Rarely, patients may experience respiratory distress requiring ventilatory support. Despite this seemingly severe constellation of symptoms, there have been no documented deaths due to NSP. NSP can present similar to other disorders such as:
common food poisoning
seafood allergy
paralytic shellfish poisoning
ciguatera fish poisoning
pesticide poisoning
alcohol intoxication
certain psychiatric disorders.Due to the extensive list of disorders with similar symptoms, a detailed food history is necessary to make the diagnosis. Management and treatment
Treatment for NSP is mostly supportive with monitoring and symptom management. Intravenous fluids and observation of respiratory function are the mainstay of treatment along with pain control. Activated charcoal can be given if the patient presents within four hours of consumption to decontaminate the gastrointestinal tract. Currently, there is no specific antidote for brevetoxins, however there may be a role for mannitol (the primary treatment for ciguatoxin, a dinoflagellate-produced toxin found in some species of fish) or brevatal, a natural antagonist of brevetoxin produced by K. brevis. Though public health policy differs by state, measures are taken to prevent shellfish poisoning outbreaks.
