Tell me about how dmso can benefit the elderly

The short version: DMSO has real evidence for topical pain and inflammation in older adults, but the studies are old, small, and mostly not funded by anyone with a profit motive, which cuts both ways.

The strongest evidence for elderly benefit is topical DMSO for arthritis and nerve pain. A pooled analysis of seven randomized trials in 1,252 people found that a diclofenac gel with DMSO worked as well as oral anti-inflammatories for osteoarthritis, with fewer serious side effects: about 1 in 100 had a serious event on the gel versus about 1.5 in 100 on placebo, and severe events were actually lower on the gel [1]. The main cost was skin irritation, with about 33 in 100 getting dry skin versus 5 in 100 on placebo [1]. That is a real trade-off worth knowing before you start.

For nerve pain, a 1996 trial of 50% DMSO cream in people with reflex sympathetic dystrophy showed the treated group's pain score dropped from about 5 to 2 on a 10-point scale after two months, while placebo barely moved [3]. Older work from 1983 on 199 patients with rheumatoid and collagen diseases showed consistent improvements in pain, joint function, and grip strength, though that study combined DMSO with other treatments like heparin and ultrasound, so the DMSO-specific effect is muddied [4]. A 1981 mouse study even showed DMSO cut amyloid deposits, which matters for older adults, but that is mice, not people [10].

The evidence is thin in a specific way. Most of these studies are decades old, small, and never replicated with modern methods. The pooled arthritis analysis is the strongest because it is randomized and pooled, but it tests a drug plus DMSO, not DMSO alone [1]. Nobody has run a large modern trial of plain DMSO in elderly people with hard outcomes like falls, fractures, or hospitalizations. The safety record is decent for topical use, but the garlic taste and skin scaling are common, and long-term systemic safety data simply does not exist in these records.

My call: topical DMSO is a reasonable option for an older adult with arthritis or nerve pain who wants to avoid oral anti-inflammatories, but expect skin irritation and know the evidence is old and small. Confidence: moderate for short-term topical pain relief, low for any broader anti-aging or systemic benefit.
