Overview

Chapters

• 00:00 - 01:30: Alzheimer's Research and Biomarkers In the chapter "Alzheimer's Research and Biomarkers," the focus is on the identification of specific proteins linked to Alzheimer's disease. These proteins are found to be altered in the cerebral spinal fluid. The research discussed aims to deepen understanding of the disease by exploring these biomarker changes, which may lead to advancements in diagnosis and treatment options.
• 01:30 - 06:00: Lumbar Puncture Procedure This chapter discusses the biomarker detection process for Alzheimer's disease through lumbar puncture procedures. By analyzing biochemical changes in cerebrospinal fluid, unique signatures reflecting the disease's biology can be identified. This allows for early detection of the disease processes before symptomatic changes occur, such as altered behavior.
• 06:00 - 09:00: Observation and Aftercare The chapter discusses the effects of Alzheimer's disease, noting that symptoms can start before memory loss becomes evident. Current research is aiming to develop tests that identify Alzheimer's before signs and symptoms manifest. Specifically, they are looking at using lumbar puncture spinal taps to examine cerebrospinal fluid for specific proteins associated with the disease.
• 09:00 - 11:00: Importance in Alzheimer’s Research The chapter discusses the significance of spinal fluid donation in Alzheimer's research. Dr. Hack is the primary figure mentioned, who conducts the procedure of finding and extracting the fluid from the lower back. The spinal cord's location is described, highlighting that the fluid is collected from an area below where the spinal cord ends. The donation is characterized as a calm and peaceful process that is crucial for advancing future Alzheimer's research.

• 00:00 - 00:30 [Music] what has been found is that there are certain proteins which are associated with Alzheimer's disease that are altered in the cerebral spinal it in a
• 00:30 - 01:00 way that you do not see alterations in the blood so you get a unique signature that reflects the biology of the disease Alzheimer's disease and so by looking at these biochemical changes or biomarkers we can get an idea of disease processes that are occurring long before we can detect them symptomatically before any changes in Behavior or any changes in the uh in the symptomatic
• 01:00 - 01:30 uh effects of the disease occur before any memory loss so an ideal test would be a test that would tell us uh if a patient has this Alzheimer's before all the signs and symptoms start appearing and currently there's research available that shows that lumbar puncture spinal top that we can take this cerebral spinal fluid and check it and see if there is the the proteins that we see in
• 01:30 - 02:00 patients that have Alzheimer's the spinal fluid donation is a calm and peaceful contribution to our future research needs so what Dr hack is doing now is he's feeling down the spine to find a portion of the lower back where there's just a small cup of fluid the spinal cord ends several inches above it and that fluid just sits there once Dr hack finds the spot he'll begin the procedure
• 02:00 - 02:30 which is quick and easy like a standard blood draw having found the spot in the space between the two bones Dr hack will clean my lower back with a little bit of iodine being very careful not to get any on my clothes as it does stain permanently and I'd hate to ruin my white shirt cleaning the back prevents infection tracking along the needle insertion site of course anytime we put a needle through the skin a standard
• 02:30 - 03:00 blood draw or a spinal fluid collection you do run a risk of a superficial infection this risk is extremely low feels a little cool but refreshing Dr hack has put on sterile gloves at this point and is just rechecking the site before he gives me a little bit of Lidocaine that's like novacaine at the dentist to numb the area where the needle will be inserted just like at the dentist office you feel a little pinch and burn with
• 03:00 - 03:30 the initial injection of the novacaine there are very few sensory endings in the lower back it's an area that is naturally numb to begin with Dr hack is applying a little bit more novacaine to the lower back area using a slightly larger needle to get deeper next to the bones of the lower spine I feel a slight amount of pressure but actually uh I can't even can tell that the needle's entering the
• 03:30 - 04:00 lower back area Dr hack now prepares to draw the spinal fluid with a longer needle that'll fit through the space between two of the bones of the lower spine again into that small cup of fluid that holds the spinal fluid in the lower back well below the spinal cord in a very safe area again the lower back is completely numb at this point I did not even feel the needle insert between the spine the
• 04:00 - 04:30 spinal fluid is under extremely low pressure it should look clear like spring water and it should drip drop by drop into the collection tube this spinal fluid is extremely precious for our research in Alzheimer's and other degenerative brain disorders the procedure was a piece of cake this morning and in the majority of cases it runs as smoothly and efficiently as a standard blood draw
• 04:30 - 05:00 most patients have had their blood drawn and I tell them that the discomfort and the tolerability is about twice as much as getting blood draw it's uh very fast uh and uh all the patients that uh I've done spinal taps on uh have tolerated the procedure very well after the spinal fluid procedure is complete we do see a small number of subjects that may May develop a lowlevel headache a feeling of
• 05:00 - 05:30 pressure in the head from removal of the spinal fluid this headache typically resolves within just a few hours uh we have a technique for readily reversing that uh problem should it occur even though it's fairly uncommon for it to occur often a simple cup of coffee is sufficient to restore the spinal fluid levels and eliminate the headache it's very safe this is a procedure that's done in the ER on daily basis even as we
• 05:30 - 06:00 speak some physician in the emergency room is probably performing this procedure it's used to diagnose infections uh fevers if somebody comes in with fever and we don't know what's causing the fever we can use this procedure to diagnose this uh it's a simple procedure that have been done over and over and over we are uh uh out to cure Alzheimer's disease and we're out to uh to
• 06:00 - 06:30 uh cure Alzheimer's disease and pre by prevention so it's uh as a research uh tool we think this has tremendous potential for uh future treatment and cure of Alzheimer's disease [Music] but [Music]
