We ask a lot of our spines. They keep us upright, they bend into myriad positions, and they protect our spinal cord, a huge job by itself. And they go the distance, doing all of those things, if we’re lucky, well into our 90s. But the longer we live, the more we wear out our spines. That’s where Dr. Jian Guan comes in. He handles complicated spinal issues that don’t get better with rest, exercise or physical therapy. After medical school and residency, he did a fellowship in complex spinal neurosurgery at the Lahey Clinic in Massachusetts, one of the top U.S. spine centers. Many of the patients that Dr. Guan sees have been in accidents or experienced other trauma. But many others are the victims of poor posture and inactivity, two things that are detrimental to spine health. In this episode, Dr. Guan talks about how important it is to get up and out of chairs in front of our computers and how to sit when we must. Hit play and learn how to keep an incredible structure healthy for the long run.

Alzheimer’s disease is a progressive neurological disorder that affects the brain’s function and causes a gradual decline in cognitive function, including memory, thinking, and behavior. It is the most common cause of dementia, accounting for approximately 70% of all cases of dementia.

The exact cause of Alzheimer’s disease is not fully understood, but it is believed to be a combination of genetic, environmental, and lifestyle factors. The disease is characterized by the accumulation of abnormal proteins in the brain, which interfere with the communication between brain cells and cause their death over time.

There is no cure for Alzheimer’s disease, but there are medications available that can help manage the symptoms and slow the progression of the disease. These medications work by increasing the levels of neurotransmitters in the brain, which can improve communication between brain cells and delay the onset of more severe symptoms.

Lifestyle changes, such as regular exercise, a healthy diet, and cognitive stimulation, may also be helpful in managing the symptoms of Alzheimer’s disease. Additionally, it is essential to work closely with a healthcare professional experienced in treating Alzheimer’s disease to develop an appropriate treatment plan.

While Alzheimer’s disease is a devastating condition that affects millions of people worldwide, early detection and treatment can help individuals maintain their quality of life for as long as possible.

Sudden Sensorineural Hearing Loss (SSHL), or sudden deafness, is a rapid loss of hearing. SSHL can happen to a person all at once or over a period of up to 3 days. It should be considered a medical emergency. Hearing loss affects only one ear in 9 out of 10 people who experience SSHL. Many people notice it when they wake up in the morning. Others first notice it when they try to use the deafened ear, such as when they make a phone call. Still others notice a loud, alarming “pop” just before their hearing disappears. People with SSHL often experience dizziness or a ringing in their ears (tinnitus), or both.

Dr. Abbas Anwar, a native of Southern California, is a board certified otolaryngologist – head and neck surgeon, at the Pacific Eye, Ear & Skull Base Center, Pacific Neuroscience Institute.

Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep. Obstructive sleep apnea (OSA) is the most common type of sleep apnea, characterized by repeated episodes of partial or complete blockage of the airway during sleep. These blockages occur when the muscles at the back of the throat relax excessively, causing the airway to narrow or close, and momentarily stopping breathing. This condition contrasts with central sleep apnea, where the brain fails to send proper signals to the muscles that control breathing. When the brain is deprived of oxygen during sleep, OSA can lead to a number of serious conditions affecting not only quality of life, but brain health and function. It is important to seek medical attention.

Omid B. Mehdizadeh, MD, is an otolaryngology-head & neck (ENT) surgeon with particular expertise in voice, swallowing and airway conditions at Pacific Neuroscience Institute (PNI). A Los Angeles native, his career has spanned treating world-class opera and Broadway singers to surgical mission trips serving underprivileged and indigenous populations of Central America. Outside PNI, he has focused his time on educating medical and undergraduate students and providing medical care to disenfranchised populations through community clinics.

Sandra Narayanan, MD, Vascular Neurologist and Neurointerventional Surgeon at the Pacific Stroke and Neurovascular Center at Pacific Neuroscience Institute, explains the difference between hemorrhagic and ischemic stroke.

The main difference between the two types of stroke is the underlying cause of the brain damage. In ischemic stroke, the damage is caused by a lack of blood supply, while in hemorrhagic stroke, it is caused by bleeding into the brain tissue. Both types of stroke are medical emergencies and require immediate medical attention to prevent further damage and improve outcomes.

For decades, people thought physical exercise benefited only the body. But every year we learn how incorrect that was, and Dr. David Merrill, director of PNI’s brain health center, is one of the people pushing our knowledge forward. It turns out that exercise builds the brain by prompting the production of brain derived neurotrophic factor, or BDNF. “Trophic” compounds cause things to grow, and BDNF helps create new connections among neurons, which is how we learn. In short, BDNF is fertilizer for the brain, Dr. Merrill says. In a perfect world, we would be able to take BDNF in a pill, like a vitamin. But it’s a big, clunky molecule that doesn’t pass easily from blood to brain. Exercise gets the job done, boosting BDNF and keeping our brains nimble. That fact makes exercise crucial as we age. Pumping iron, and therefore pumping up BDNF, promotes brain plasticity: the ability to change, grow and adapt to the insults that come with growing older. Listen to this episode to hear how you can boost BDNF through exercise and stay sharp into your golden years.

There are no specific diets that have been shown to reduce the progression of PD. However, there is good reason to believe that a well-balanced, nutritious diet would be best. In those without other medical conditions, the Mediterranean-DASH Intervention for Neurogenerative Delay (MIND) diet may be of benefit in Parkinson’s as well since both are neurodegenerative diseases such as Alzheimer's disease.
