Today an influential but sadly flawed 'consensus' pours water on adverse #BrainHealth risk and #neurodegenerative disease/ #dementia in former contact sport athletes.

Meanwhile ⬇️
"But it's a consensus of experts!"

Nobody can be an expert on everything, not even #CISG

Recognising this, Statement authors commissioned reviews by selected specialist 'expert' authors to review literature*, led by small subgroups of #CISG panel

1/ Image
These sub-groups then fed back outcomes from the review processes, which wider Statement authors voted on, so producing 'consensus' positions.

What does this mean?

It means that for late effects, by example, only 7/31 Statement authors actually reviewed the literature

Ten lesser-known symptoms that could point towards a diagnosis of brain tumor

June 8th is celebrated as “World brain tumor day” to raise awareness about brain tumors. I would like to focus on the symptoms, presence of which, can make one suspect the presence of brain tumor.…
Common symptoms of brain tumor include headache, vomiting, reduced alertness, fits & paralysis. However, in several cases, these classical symptoms may be missing. It is important to know the lesser-known symptoms of brain tumors so that they can be diagnosed & treated early.
1. Increase in hat and shoe size over time- A tumor of pituitary gland of brain producing excess growth hormone (GH) causes a condition known as acromegaly, which can result in increasing head and feet size, necessitating a need for larger hats and bigger shoes.

Type 2 diabetes is associated with increased risk of developing dementia

1. Those diagnosed with diabetes before age 60 years had a nearly threefold increased risk for dementia compared to those who never developed diabetes, as per a recent study.
#MedTwitter #diabetes… Image
2. Those aged 60-69 years at diabetes diagnosis had 73% higher risk of developing dementia and those aged 70-79 years at diabetes diagnosis had 23% higher risk of developing dementia.
The relationship with dementia was not significant for those aged 80 years and older.
3. Mechanisms include glucose toxicity, insulin resistance & microvascular dysfunction of the central nervous system.
Glucose toxicity and microvascular dysfunction are associated with increased inflammatory & oxidative stress, leading to increased blood–brain permeability.

Concerns regarding exploitation of the #agedcare funding system & repeated calls for accountability & transparency R well founded. A brief (by all means not comprehensive) history on #rorting or 'maximising' in aged & home care @JasonWardCICTAR @anmf_federal
(2012) Nursing homes: The manner in which govt was prepared to turn a blind eye to #rorting in #agedcare was revealed when employees in the Health dept blew the whistle on ABC @4corners in 2012…
Nurses working for the dept to oversee payments claimed that #agedcare homes were "treating residents like a cash cow". The dept was not acting on info they supplied. They were told to "look the other way, tick it all, let it go through" #rorting

1. Today at work: Conversed with patients in Tamil, Telugu, Bangla, Hindi, English, Somali & Arabic during ward/ICU rounds & OPD.
Brought smiles on patient's faces as well. I love interacting with people/patients in their own languages as they love listening to own languages.…
2. I have seen agitations against various languages in many states, which are futile. It is always good to learn more languages, as it is a win-win situation.
(below pictures are from the internet) ImageImage
3. Speaking two languages, moreover, delays the age of onset of dementia by an average of 4.5 years. This benefit is seen in educated as well as illiterate people.…

Regular internet usage is associated with lower risk of dementia in older people

1. The prevalence of dementia is increasing with an increase in longevity. Prevention is preferred as there is no cure for Alzheimer's disease.
#dementia #MedTwitter #NeuroTwitter #Internet
2. 18,154 adults aged 50-65 were followed up for a maximum of 17.1 (median=7.9) years.
Regular internet usage was associated with approximately half the risk of dementia compared to non-regular usage.
Educational status did not play any role in this association.
3. In addition, additional periods of regular usage were associated with significantly reduced dementia risk.
However, estimates for daily hours of usage suggested a U-shaped relationship with dementia incidence. The lowest risk was observed among adults with 0.1-2 hours of usage

In order for ketogenic diets to be offered as a treatment for Alzheimer's disease and covered by insurance, several things would need to happen. (1/11)
First, large-scale clinical trials would need to be conducted to demonstrate the safety and efficacy of ketogenic diets for Alzheimer's disease. (2/11)
These trials would need to include diverse patient populations and be well-designed to control for confounding variables. (3/11)

Day 2 @theNASEM workshop
The highlight from day 1: LaToya, a CNA, gave a moving, honest, courageous account of being a direct care worker. “The ice cream truck should not be a luxury.”
- hours & pay are bad, the work is hard & they love & care their patients & their dignity ImageImage
@theNASEM First up- @EspinozaNotes from @PHInational
The intense focus on direct care workers, paying people a living wage, improving working conditions so that we can also improve patient care during this event has given me so much hope Image
“Social determinants of success at work” is one phrase that stuck out to me yesterday.
@mad_sters doing critical work in this area for direct care workers
But I think about it for others who work in our system too.

B12 is an important water-soluble organic compound that plays a critical role in the health of our brains. It is involved in DNA synthesis, methylation, and cellular metabolism, which means it is necessary for the proper functioning of our cells. (1/21)
B12 deficiency is a major concern, as it can lead to megaloblastic anemia and neurological problems. But did you know that inadequate #B12 or subclinical deficiency is also very common? (2/21)
It's seen at all ages but definitely in elderly populations. This can be particularly worrisome for those with Alzheimer's disease (AD), as several studies have shown an association between B12 deficiency and #AD. (3/21)

One in five people suffer from hearing loss

1. Yes, you heard it right.
This information was obtained by a study published in The Lancet journal in Mar 2021.
An estimated 1·57 billion people globally had hearing loss in 2019.…
2. Although hearing loss is common in old ages, globally 70 million children aged 0–15 years also live with this condition. Otitis media and meningitis are risk factors for hearing loss in children.
38% of people with hearing loss were less than 50 years old.
3. When unaddressed, childhood hearing loss can affect spoken language development, literacy skills, and education, which might affect cognition and social wellbeing.
Older people with hearing loss have a higher risk of developing #dementia, including #AlzheimersDisease.

People with #dementia have protein build-up in astrocytes that may trigger abnormal antiviral activity and memory loss. Abnormal immune activity in non-neuronal brain cells called astrocytes is sufficient to cause cognitive deficits in dementia. Image
#2. The discovery could lead to new treatments that reduce excess immune activity in astrocytes and their detrimental effects on other brain cells and cognition.
#3. To understand the causes of memory loss at the molecular level, analyzed gene expression and found high levels of antiviral gene activities, even though no virus was present in the brain. Astrocytes produced excessive amounts of immune messengers called chemokines, which

The largest underlying cause of recent non-COVID-19 excess deaths in Scotland has been “Other causes”

The “Other causes” category also includes deaths which
have an unascertained cause whilst being investigated by the Procurator Fiscal

Why do we need seniors to have access to a ketogenic diet to help ward off dementia? Because telling them to eat more fish and blueberries is woefully insufficient! Think I am making this up? I am not. It's time for a thread on a recent study. 🧵 (1/19)
The objective of this study was to examine the relationship between consumption frequency of meat, fish, fruits, and vegetables and long-term risk of dementia and Alzheimer’s disease while taking into account the possibility of protopathic bias (i.e., reverse causation). (2/19)
The researchers analyzed data from the Three-city study, which followed 5,934 volunteers aged 65 and over for 12 years. (3/19)

Perceived stress increases the risk of cognitive decline and dementia

1. A recent study looked at the association of perceived stress and incidence of cognitive impairment in a long-term follow up study…
2. 24,448 people (median age 64 years) were followed up for >15 years. Elevated levels of perceived stress (dichotomized as low stress vs elevated stress) was associated with 1.37 times higher odds of poor cognition.
3. The association of the change in the Perceived Stress Scale score with incident cognitive impairment was significant in both the unadjusted model (OR, 1.62) and after adjustment for sociodemographic variables, cardiovascular risk factors, and depression (AOR, 1.39).

1/To call it or not to call it? That is the question!

Do you feel a bit wacky & wobbly when it comes to calling normal pressure hydrocephalus on imaging?

Here’s a #tweetorial about imaging NPH!

#medtwitter #meded #neurotwitter #neurorad #radres #dementia #neurosurgery #FOAMed
2/First, you must understand the pathophysiology of “idiopathic” or iNPH. It was first described in 1965—but, of the original six in the 1965 cohort, 4 were found to have underlying causes for hydrocephalus.

This begs the question—when do you stop looking & call it idiopathic?
3/Thus, some don’t believe true idiopathic NPH exists. After all, it’s a syndrome defined essentially only by response to a treatment w/o ever a placebo-controlled trial.

However, most believe iNPH does exist--but its underlying etiology is controversial. Several theories exist

Followed by spikes in #ExcessDeaths

Does correlation = causation ?

Since the roll out of the first #COVID19 booster in September 2021, there has been 50,000 deaths attributed to ‘Covid’

6,000 #Unvaccinated
44,000 #Vaccinated
30,000 #Boosted

53 Million boosters - and STILL we had 44,000 Covid deaths in the vaccinated!
