Adderall and Mydayis are trade names for a combination drug called mixed amphetamine salts containing four salts of amphetamine. The mixture is composed of equal parts racemic amphetamine and dextroamphetamine, which produces a (3:1) ratio between dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine. Both enantiomers are stimulants, but differ enough to give Adderall an effects profile distinct from those of racemic amphetamine or dextroamphetamine, which are marketed as Evekeo and Dexedrine/Zenzedi, respectively. Adderall is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is also used illicitly as an athletic performance enhancer, cognitive enhancer, appetite suppressant, and recreationally as a euphoriant. It is a central nervous system (CNS) stimulant of the phenethylamine class.Adderall is generally well tolerated and effective in treating the symptoms of ADHD and narcolepsy. At therapeutic doses, Adderall causes emotional and cognitive effects such as euphoria, change in sex drive (loss of sex drive), increased wakefulness, and improved cognitive control. At these doses, it induces physical effects such as a faster reaction time, fatigue resistance, and increased muscle strength. In contrast, much larger doses of Adderall can impair cognitive control, cause rapid muscle breakdown, provoke panic attacks, or induce a psychosis (e.g., paranoia, delusions, hallucinations). The side effects of Adderall vary widely among individuals, but most commonly include insomnia, dry mouth, loss of appetite, and weight loss.
Spinal extradural haematoma or spinal epidural hematoma (SEH) is bleeding into the epidural space in the spine. These may arise spontaneously (e.g. during childbirth), or as a rare complication of epidural anaesthesia or of surgery (such as laminectomy). Symptoms usually include back pain which radiates to the arms or the legs. They may cause pressure on the spinal cord or cauda equina, which may present as pain, muscle weakness, or dysfunction of the bladder and bowel. Pathophysiology
The anatomy of the epidural space is such that spinal epidural hematoma has a different presentation from intracranial epidural hematoma. In the spine, the epidural space contains loose fatty tissue and a network of large, thin-walled veins, referred to as the epidural venous plexus. The source of bleeding in spinal epidural hematoma is likely to be this venous plexus. Diagnosis
The best way to confirm the diagnosis is MRI. Risk factors include anatomical abnormalities and bleeding disorders. Treatment
Treatment is generally with emergency surgery. The risk following epidural anaesthesia is difficult to quantify; estimates vary from 1 per 10,000 to 1 per 100,000 epidural anaesthetics. == References ==
