12 Most Common Causes Of Memory Loss

This suggests that tilt table responses may not be the best way to select patients for pacing. Recording of spontaneous asystole or severe bradycardia with an ILR seems much more appropriate, and patients such as the one shown in fig 7B​7B have done well with pacing. However, almost no patient had a recurrent symptom ECG correlation (SECGC) in the Holter group (which corroborates findings of very low yield https://ecosoberhouse.com/ of SECGC, and therefore diagnostic yield, in other Holter studies in syncope16). A perfect diagnostic technology for T‐LOC would be able to discriminate reliably between syncope, epilepsy, and psychogenic seizures. This would require long term ambulatory monitoring of heart rhythm, blood pressure, and EEG. Figure 6 Methods of obtaining objective physiological monitoring data in patients with T‐LOC.

Brain tumors can cause headaches and physical problems, but they can also affect our memory and personality at times. Depending on the severity and type of tumor, treatment can often relieve these symptoms. A TIA, also known as a “little stroke” (although that isn’t completely accurate medically), is a brief blockage in the brain that can cause lapses in memory, along with other stroke-like ptsd blackouts symptoms. Symptoms usually resolve on their own, but treatment is important to prevent future strokes. Similar to pregnancy, the hormonal changes in menopause can bring chaos to thought processes and disturb sleep, which also impacts your cognitive processes. Some physicians prescribe hormonal supplements or other treatments to relieve the temporary symptoms of menopause.


MCI can also be an early sign of a more serious memory issue, so it’s important to see a doctor regularly. Sometimes, memory loss can be linked to specific causes and even be a sign of a bigger problem. If you’re wondering if you or a loved one should see a doctor about memory loss, here’s what you need to consider. Diabetes can also damage blood vessels, increasing your heart disease and stroke risk. Without proper blood flow to your brain, your memory may suffer.

what causes blackouts and memory loss

Medications for related issues like anxiety, depression or sleep disorders may help address memory loss after stroke. In classic studies of hospitalized alcoholics by Goodwin and colleagues (1969a,b), 36 out of the 100 patients interviewed indicated that they had never experienced a blackout. In some ways, the patients who did not experience blackouts are as interesting as the patients who did. What was it about these 36 patients that kept them from blacking out, despite the fact that their alcoholism was so severe that it required hospitalization?

Causes of Memory Loss

Some people have anxiety in certain situations, like this test-taking example. Others have a more pervasive generalized anxiety disorder that continually interferes with healthy functioning, including memory. Identifying and treating anxiety can significantly improve quality of life, and possibly memory, as well. While Alzheimer’s and other kinds of dementia are responsible for many cases of memory loss, the good news is that there are other, non-permanent factors that can also cause memory loss.

If you blackout, you may also be at risk of injury from falling over. Healthdirect Australia is a free service where you can talk to a nurse or doctor who can help you know what to do. It can also be progressive, meaning it happens repetitively and worsens gradually over time. The word “memory” describes several interconnected abilities. Those abilities rely on many different areas of your brain working together properly.

Mild Cognitive Impairment

The researchers allowed the rats to forage for food for 15 minutes in a symmetric, Y-shaped maze and measured the animals’ hippocampal activity using tiny wires (i.e., microelectrodes) implanted in their brains. Figure 3 displays the activity of an individual CA1 pyramidal cell. The activity—which corresponds to the middle portion of the lower left arm of the maze—is shown before alcohol administration (A), 45 to 60 minutes after alcohol administration (B), and 7 hours after alcohol administration (C).

The hippocampus receives information from a wide variety of brain regions, many of them located in the tissue, called the neocortex, that blankets the brain and surrounds other brain structures. As is clear from patient R.B., removing CA1 pyramidal cells from the circuitry prevents the hippocampal memory system from doing its job. Alcohol interacts with several other drugs, many of which are capable of producing amnesia on their own.
