My thoughts exactly. I actually think it can improve these functions.
Do steroids hinder cognitive performance and memory?

My thoughts exactly. I actually think it can improve these functions.
You can't base your knowledge on the wack anecdotes and introspections of the commenters in this thread about this subject, so I thought I'd provide you with a little bit of research. Since you'll find this thread by googling about this subject, I think it's quite important for the readers to get this information. That's why I find this 5year BUMP necessary.

Cognitive Deficits in Long-Term Anabolic-Androgenic Steroid Users by Gen Kanayama et al.
Background
Millions of individuals worldwide have used anabolic-androgenic steroids (AAS) to gain muscle or improve athletic performance. Recently, in vitro investigations have suggested that supraphysiologic AAS doses cause apoptosis of neuronal cells. These findings raise the possibility, apparently still untested, that humans using high-dose AAS might eventually develop cognitive deficits.
Methods
We administered five cognitive tests from the computerized CANTAB battery (Pattern Recognition Memory, Verbal Recognition Memory, Paired Associates Learning, Choice Reaction Time, and Rapid Visual Information Processing) to 31 male AAS users and 13 non-AAS-using weightlifters age 29-55, recruited and studied in May 2012 in Middlesbrough, UK. Testers were blinded to participants’ AAS status and other historical data.
Results
Long-term AAS users showed no significant differences from nonusers on measures of response speed, sustained attention, and verbal memory. On visuospatial memory, however, AAS users performed significantly more poorly than nonusers, and within the user group, visuospatial performance showed a significant negative correlation with total lifetime AAS dose. These were large effects: on Pattern Recognition Memory, long-term AAS users underperformed nonusers by almost one standard deviation, based on normative population scores (adjusted mean difference in z-scores = 0.89; p = 0.036), and performance on this test declined markedly with increasing lifetime AAS dose (adjusted change in z-score = −0.13 per 100g of lifetime AAS dose; p = 0.002). These results remained stable in sensitivity analyses addressing potential confounding factors.
Conclusions
These preliminary findings raise the ominous possibility that long-term high-dose AAS exposure may cause cognitive deficits, notably in visuospatial memory.

Now don't panic too much, a longitudinal correlational research would be MUCH better to determine the cognitive effects of AAS abuse. Strong first post btw.
