Sacks et al. (2005) reported the case of a 72-year-old man, described as professionally successful, intelligent, and cultivated, with polymyalgia rheumatica, who after being treated with prednisone developed a psychosis and dementia , which several behavioral neurology and neuropsychiatry consultants initially diagnosed as early dementia or Alzheimer's disease .  Large dosage variations in the patient's medication (including a self-increased dosage from 10 mg/day to as much as 100 mg/day for at least 3 months) produced extreme behavioral changes, from missed appointments to physical altercations, and eventually admission to a psychiatric ward and later to a locked Alzheimer facility. During this time, neuropsychological testing showed a decline in the patient's previously superior IQ as well as deficits in memory, language, fluency, and visuospatial function, which given the patient's age was considered to be compatible with early dementia. When the steroid treatment ended after a year, the patent's confusion and disorganized appearance stopped immediately. Within several weeks, testing showed strong improvement in almost all cognitive functions. His doctors were surprised at the improvement, since the results were inconsistent with a diagnosis of dementia or Alzheimer's. Testing after 14 months showed a large jump in Full Scale IQ from 87 to 124, but mild dysfunction in executive function, memory, attentional control, and verbal/nonverbal memory remained. 
I get 2, 4 and 5 and I’m completely natural. I have had people accuse me of taking steroids many times and it pissed me off. It gets me to the point where I want to take steroids just so that I can say “Now this is me on steroids fckers!”. Lol. But nah I get a lot of acne outbreaks naturally and I have had many stretch marks as well as abnormally fast muscle gains. I’m a very lean person and when I stop working out I’m capable of drastically going from jacked to skinny as heck. When I start back up again I blow up quick. Another thing I’ve noticed is my pumps are naturally a lot more intense then the average lifter. Like my shoulders blow up like bowling balls and veins and shreds show up all over them along with my arm’s and chest. I’ve had a tone of people accuse me of taking steroids because of these factors. I also had a relative hug me once and say I was jacked and as solid as steal. He said only steroids do that. (He took steroids in the past) But it is to my understanding that muscle is solid… or at least a lot more solid than fat. At the time I was taking creatine and l-arginine with citrilline malate (which is a precursor to arginine) and a lot of BCAA’s.
