Thankfully, Lyme disease is rare in Singapore. But sometimes, a
supposedly low rate could be unfortunately due to under diagnosis
and lack of awareness, rather than actual non-existence. Lyme
disease is terrifying because for many (some say most) sufferers,
the subtly debilitating symptoms persist for the rest of one's
life, regardless of medical treatment.

A polyneuropathy that involves shooting pains, numbness, and
tingling in the hands or feet may develop. A neurologic syndrome
called Lyme encephalopathy is associated with subtle cognitive
difficulties, insomnia, a general sense of feeling unwell, and
changes in personality. Chronic encephalomyelitis, which may be
progressive, can involve cognitive impairment, brain fog,
migraines, balance issues, weakness in the legs, awkward gait,
facial palsy, bladder problems, vertigo, and back pain. In rare
cases, untreated Lyme disease may cause frank psychosis, which has
been misdiagnosed as schizophrenia or bipolar disorder. Panic
attacks and anxiety can occur; also, delusional behavior may be
seen, including somatoform delusions, sometimes accompanied by a
depersonalization or derealization syndrome, where the patients
begin to feel detached from themselves or from reality.
