Oxygen Therapy May Reduce Dementia Risk in COPD Patients

Breathing in extra oxygen enhances blood vessel function in the brains of people with chronic obstructive pulmonary disease (COPD), according to a new study published in the journal Experimental Physiology.

The findings show why oxygen therapy may help reduce incidence of dementia among patients with lung disease.

COPD is a collective term for a group of lung conditions that cause long term breathing problems. Patients with this condition are at greater risk of memory loss and dementia, commonly believed to be the result of reduced brain oxygen levels due to poor lung function.

Some studies have shown that giving COPD patients additional oxygen can lower their risk of developing dementia, but, until now, the mechanisms underlying this positive effect have not been fully investigated.

In a new study, researchers used ultrasound to view and measure blood flow in the brain in COPD patients at rest, before and during delivery of additional oxygen. The oxygen was delivered through the nasal passage for 20-30 minutes.

In addition to measuring blood flow in the brain, the research team also analyzed the connection between brain activity and blood flow in the brain. To do this, patients began with their eyes shut, then had to open them and read standardized text. This experiment was designed to boost activity in the brain, and in turn, increase blood flow in the brain to provide adequate oxygen supply.

The researchers compared the ultrasound results with a measurement of blood oxygen levels which allowed them to estimate how much oxygen delivery to the brain increased during the open-eyes reading test.

They found that blood flow and oxygen delivery to the brain was significantly increased during reading. This was due to blood vessels in the brain becoming dilated in response to the greater oxygen demand when the brain was active. Researchers concluded that when COPD patients receive additional oxygen it improves the function of blood vessels in the brain.

However, COPD patients typically use this extra oxygen therapy throughout the day and for long periods of time, potentially years. This experiment was not able to determine the impact of long term oxygen therapy on the function of blood vessels in the brain.

But despite these potential limitations, this work has set the foundation for the researchers to study the biological systems that control oxygen delivery to the brain.

COPD affects primarily middle-aged or older adults who smoke. Symptoms often include breathlessness and a chesty “smokers cough.”

Hair Pulling, Nail Biting, Skin Peeling and Biting

All my life I’ve bitten my nails. It’s caused me a lot of trouble, especially with my bipolar mother who has always thought screaming and shouting at me (and often a smack when I was younger) would make me stop.At around 7 I also started biting and peeling the skin on my fingers which has caused a lot of social and health issues for me from being to ashamed to join in with prayers at school, to getting my fingers getting a fungal infection causing long lasting damage to my fingers.Soon after I started to pull out the tiny hairs on my legs during school assembles and by 12 I began to pull my eyebrow hair out.How can I stop doing this to myself? I don’t even realise I’m doing it half the time (I started biting the skin around my fingers just writing this and caused it to bleed a little). I’m afraid to bring this up with my parents because of how they have reacted in the past and I’m far too embarrassed to ask anyone I would typically trust. It has severally impacted how I interact with …

Painful Memories Evoke More Intense Emotions in Those With Depression

People with major depressive disorder (MDD) experience more intense negative emotions while recalling painful memories compared to non-depressed people, according to a new study published in the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.And although those with MDD were able to turn down their negative emotions about as well as non-depressed people, they used different brain circuits to do so.The new findings pinpoint brain differences in MDD associated with the processing of autobiographical memories — one’s memories of personal events and knowledge of one’s life — that help us develop our sense of self and guide our interactions with the world around us.“This study provides new insights into the changes in brain function that are present in major depression,” said journal editor Cameron Carter, M.D. “It shows differences in how memory systems are engaged during emotion processing in depression and how people with the disorder must regulate these systems i…
