LAKEPORT, Calif. – Ruth Lincoln, clinical nurse and staff educator at Sutter Lakeside Hospital, announces a Stroke Support Group kickoff meeting scheduled from 1 p.m. to 2 p.m. on Monday, Sept. 24.
The meeting will take place in the Hospital Conference Room at Sutter Lakeside Hospital. Community members are welcome and the meeting is free of charge.
The California HealthCare Foundation, which publishes California Healthline, reported in January of 2012 that Lake County residents have the second highest rates statewide of a stroke prevention procedure called carotid endarterectomy.
Because of the prevalence of strokes in Lake County, Sutter Lakeside Hospital decided to create a support group for stroke survivors and their families and friends.
The first meeting, scheduled to take place on Sept. 24, will provide an opportunity for community members affected by stroke to meet and share stroke recovery information.
“Almost everyone is touched by family and friends who have experienced stroke, and I know firsthand the importance of connecting with available resources and services,” said Lincoln. “We would like to create a safe place for stroke survivors and their loved ones to share the information that they’ve learned as well as their experiences.”
Chief Nursing Executive Teresa Campbell added, “Sutter Lakeside Hospital is committed to making sure that our patients and their families have access to the tools that they need to recover from strokes. Studies have shown that the supportive environment of a peer group can go a long way towards improving a patient’s quality of life. We’re excited to offer this group to the public and look forward to getting to know how we can support Lake County residents and families who have been affected by strokes.”
Light refreshments will be served and all community members are welcome. RSVPs are not required. If you have questions concerning the kickoff meeting, please contact Ruth Lincoln at 707-262-5032.

Turning the volume up too high on your headphones can damage the coating of nerve cells, leading to temporary deafness, scientists from the University of Leicester have shown for the first time.
Earphones or headphones on personal music players can reach noise levels similar to those of jet engines, the researchers said.
Noises louder than 110 decibels are known to cause hearing problems such as temporary deafness and tinnitus (ringing in the ears), but the University of Leicester study is the first time the underlying cell damage has been observed.
The study has been published in the Proceedings of the National Academy of Sciences.
University of Leicester researcher Dr Martine Hamann of the Department of Cell Physiology and Pharmacology, who led the study, said:
“The research allows us to understand the pathway from exposure to loud noises to hearing loss. Dissecting the cellular mechanisms underlying this condition is likely to bring a very significant health care benefit to a wide population. The work will help prevention as well as progression into finding appropriate cures for hearing loss.”
Nerve cells that carry electrical signals from the ears to the brain have a coating called the myelin sheath, which helps the electrical signals travel along the cell.
Exposure to loud noises – i.e. noise over 110 decibels – can strip the cells of this coating, disrupting the electrical signals. This means the nerves can no longer efficiently transmit information from the ears to the brain.
However, the coating surrounding the nerve cells can reform, letting the cells function again as normal. This means hearing loss can be temporary, and full hearing can return, the researchers said.
Dr Hamann explained: “We now understand why hearing loss can be reversible in certain cases. We showed that the sheath around the auditory nerve is lost in about half of the cells we looked at, a bit like stripping the electrical cable linking an amplifier to the loudspeaker. The effect is reversible and after three months, hearing has recovered and so has the sheath around the auditory nerve.”
The findings are part of ongoing research into the effects of loud noises on a part of the brain called the dorsal cochlear nucleus, the relay that carries signals from nerve cells in the ear to the parts of the brain that decode and make sense of sounds.
The team has already shown that damage to cells in this area can cause tinnitus – the sensation of ‘phantom sounds’ such as buzzing or ringing.
The research was funded by the Wellcome Trust, Medisearch, GlaxoSmithkline and the Royal Society.
