![]() Reports of non-visual synesthesia are rare, and until now, there have been no reports of synesthesia in people with congenital blindness. The majority of synesthesia cases have reported visual experiences. However, many report symptoms for as long as they can remember.īetween 80 and 97% of people with synesthesia report color-related synesthesia. Some cases of synaesthesia occur after brain damage, drug use, or sensory loss. Synesthesia is a neurological condition in which stimulation of one sense leads to an experience in another, such as seeing colors when listening to music. They say further research is needed to understand the underlying mechanisms of synesthesia.They say their findings shed light on the role of vision in the condition.Researchers examined the first-ever reported case of a congenitally blind person with synesthesia.But the good news for people with synesthesia is that they seem to have an advantage on at least some memory tasks to begin with – meaning that even as their memory declines, they tend to start from a higher point.Share on Pinterest A new paper details the first-ever reported case of synesthesia in a congenitally blind person. Overall, these studies suggest people with synesthesia experience the cognitive effects of aging that we all do, and that these effects might even weaken some of their cross-sensory perceptions. This in turn made older synesthetes more likely to fail a synesthesia test. When they looked at what was going on more closely, the authors of the study found evidence that for people with number-color or letter-color synesthesia, the colors they associate with numbers or letters tend to fade, becoming less saturated with age. A 2017 study of 4,000 people found that older people had lower rates of self-reported synesthesia and were less likely to pass a test of synesthesia. ![]() Therefore, an older person with synesthesia would tend to have about the same memory abilities as a younger person without synesthesia, all else being equal.Īnother question worth asking is whether synesthesia itself changes with age. The researchers found that the effect of having synesthesia on enhancing memory was about the same as the effect of being young. The catch, though, is that people with synesthesia apparently start off with better memory performance on average. So in that sense, the answer is that no, synesthesia does not protect against age-related memory loss. One aspect of synesthesia that researchers have been curious about lately is how synesthesia relates to aging, and age-related changes in cognition.Ī recently published paper posed the question in its title: Does synesthesia protect against age-related memory loss?Īs it turns out, the answer depends on what exactly you mean by “protect against.” The results of the study suggest that people with synesthesia experience a decline in memory abilities as they age, just like everyone else. For example, I’ve written about how people with synesthesia apparently have more autistic traits. Synesthesia has been found to correlate with certain psychological and neurological traits that it doesn’t otherwise have an obvious connection to. We know that some people link letters with colors, or sounds with tactile sensations, but the broader implications of having synesthesia are less clear. The cross-sensory associations of synesthesia are still something of a mystery.
