why do people blackout for no reason
Heavy drinking may have lasting effects on the brain. These effects range in severity from momentary БslipsБ in memory to permanent, debilitating conditions. ItБs thought that chronic alcohol consumption can harm the frontal lobe. This is the part of the brain that controls cognitive function. The frontal lobe also plays a role in short-term and long-term memory formation and recall. Regular damage to the frontal lobe can impair your behavior and personality, how you perform tasks, and how you keep information. ItБs thought that binge drinking can impair this part of your brain. control impulses. Having even one blackout can be dangerous. According to the, alcohol delays signals in the brain that control the gag reflex and other autonomic responses. A person who has blacked out or overdosed on alcohol could throw up while sleeping due to the loss of reflex control. This could cause them to choke and suffocate on their vomit. A blackout also makes you more susceptible to injury, such as from a fall or car crash.
Taking sedatives while also consuming alcohol can increase the likelihood that you ll black out. That s because benzodiazepines like
(Xanax), and opioids like (OxyContin), activate the GABA neurotransmitter. This causes your body to slow down and become more relaxed. Like alcohol, sedatives can impair your ability to think and make memories. THC, the psychoactive compound found in marijuana, may also increase blackouts when combined with alcohol. Assessment of Blackouts. Assessment is best done by a multidisciplinary team, to avoid the problems above. Elsewhere in this website, I describe the specialist nurse-lead, multidiciplinary Rapid Access Blackouts Triage Clinic at Manchester Royal Infirmary. P The aim of this clinic is:- High Costs. Real opportunities exist for savings to invest, as the APPG report notes, The Joint Epilepsy Council has shown how improvements in epilepsy care in England could realise savings. when the economic cost or the cost in opportunities for people who could be in work but are not due to misdiagnosis or mistreatment.
When those costs are included, the estimated total cost of misdiagnosis in England rises to S134 million a year. Medico-Legal. The side effects of some [epilepsy drugs] should not be underestimated. [including] major malformations in the offspring of mothers with epilepsy can be associated with use in early pregnancy. Given the high number of misdiagnosed epilepsy cases in England, the APPG can only conclude that as a result tens of thousands of people are enduring these side-effects from drugs they should not be taking in the first place. Public Health Hazards of Misdiagnosis. This represents a major public health disaster, since up to 120,000 patients in the UK are therefore wrongly diagnosed. P Many of these will receive a trial of therapy with anticonvulsants. P This serves only to cement a misdiagnosis, since many blackouts are isolated, and even true epileptic seizures may occur only rarely in patients who have a relatively low seizure-threshold. Up to 70% of first-fit patients have syncope, usually due to fainting.
P However, in practice many doctors are tempted to treat epilepsy after a first or second seizure. P This is because of the important implications of epilepsy for education, relationships, employment, driving, insurance and childbearing. P Such a rapid resort to medication is unnecessary, since studies have shown that immediate versus delayed treatment for epilepsy has no effect on prognosis, but may substantially affect lives. P Epilepsy versus Syncope. The EEG is not diagnostic of epilepsy, especially in the over 35s. Therefore a diagnosis of epilepsy, and alternatively, a diagnosis of syncope, depend on the quality of clinical assessment, supported by simple bedside tests, such as the 12-Lead ECG. Cardiac Risks. A small number of patients with a misdiagnosis of epilepsy have a life-threatening electrical disease of the heart, such as LongQT Syndrome, Brugada Syndrome and Wolff-Parkinson-White Syndrome. P These can be detected by an ordinary 12-Lead ECG, which should be done in ALL cases.
Sorting out the different blackouts. All patients with a blackout should have a clinical evaluation and an ECG. P An ECG should never be ommitted. What should I ask? There are 6 Red Flag questions, which are given in the algorithm. P Patients with no Red Flags and a normal 12-Lead ECG can be reassured. P The 18-Week Blackouts Commissioning Pathway will include a triage level between first responders in primary care and A E, and specialist referral. What if it is just fainting? After a faint, a patient should not drive for 3 months. P Recurrent fainting can be a problem, and often there is accompanying low blood pressure. P Such patients often dont take enough salt. P This can be encouraged, and other treatment options include Midodrine, an -agonist, and pacemaker treatment in selected patients who have asystole during their attacks. P When pacemaker treatment is guided by recording a spontaneous faint using a long-term implantable ECG loop recorder, patients do very well.
