SINGAPORE (AP) — The daughter of former Singapore Prime Minister Lee Kuan Yew says her father has a rare nerve disease that makes walking difficult.

Lee Wei Ling said Sunday in her weekly column in the Straits Times that Lee has been diagnosed with sensory peripheral neuropathy. The disease affects nerves outside the central nervous system, and Wei Ling said it undermines his balance.

Wei Ling said the 88-year-old Lee's brain and muscles are working normally. Lee is walking on a treadmill three times a day to improve his balance.

Wei Ling is a medical doctor and director of Singapore's National Neuroscience Institute.
