I thought it'd be too much in the weeds. The UTexas paper goes into their prescribing data and comes out with the conclusion that calcineurin inhibitors are the only common factor in their patients who don't get dementia.

Rapamycin also does not have any evidence of efficacy on neurodegeneration, while there's evidence for CNI on other forms of neurodegeneration.

What are the side-effects of calcineurin inhibitors ?

Cyclosporine has some very serious long-term toxicity (especially renal dysfunction and hypertension) and the availability of newer biologic agents has restricted the use of cyclosporine to patients who have not responded to conventional treatment.

  *Mild tremor is common with both cyclosporine and tacrolimus use, occurring in 35 to 55 percent of patients [ 79,80 ].
  *Rarely, patients develop severe headache, visual abnormalities, and seizures. This syndrome is associated with acute hypertension and resembles hypertensive encephalopathy [ 77 ]. 
  *Posterior leukoencephalopathy is usually seen on brain imaging [ 82 ].
  *Cyclosporine may contribute to bone loss after organ transplantation [ 88 ]; this effect may be due to the induction of high bone turnover. 
  *Cyclosporine can cause hyperkalemia and hypomagnesemia, via effects on renal tubular function. Hyperuricemia and exacerbation of gout are well-described with cyclosporine.
