Researchers connected ADHD with Alzheimer's. (Dementia)

 Researchers connected ADHD with Alzheimer's. (Dementia)


New research connects ADHD with Alzheimer's. The thing that we must realize is that ADHD patients have more often social problems. Sometimes ADHD patient is "weird". And those people have problems with their social relationships. 

ADHD patients must concentrate harder to keep themselves calm than other people. If we must always concentrate on our behavior and be afraid that somebody sees something that we don't want to tell that causes stress. Stress causes high blood pressure. 

"Scientists have discovered that short-term fluctuations in blood pressure are linked to cognitive impairment and increased vascular problems in older adults. These fluctuations, overlooked in clinical treatments focusing on hypertension, also correlate with arterial stiffness. The findings suggest that monitoring blood pressure variability could serve as an early marker or intervention point for preventing dementia, even in individuals without noticeable cognitive decline." (ScitechDaily/Early Warning Sign Identified – New Research Links Fluctuating Blood Pressure to Dementia)


ADHD patients drop out more often than others outside of working life. That causes stress and those people will more often than regular people fall into some alcoholist or drug-using gang. 


The social problems cause bad lifestyles like the use of tobacco, alcohol, and unhealthy food. Tobacco causes high blood pressure, and alcohol is bad for the nervous system because it dissolves proteins that create the neuron's shell. That kind of thing can explain why ADHD patients get more often Alzheimer's than regular people. Things like too much alcohol that destroys too much and too high blood pressure are things that cause Alzheimer's. 

The fluctuation in blood pressure is also the thing that linked to dementia. When people have high blood pressure. They get drugs that decrease blood. The problem is that the blood pressure will rise between those pills. That causes fluctuation in that pressure. In that process, the blood pushes against blood vessels. And that separates plague from the walls of those vessels.

Russia shot down one of its Su-35S fighter-bombers.

Human error, or somebody who might jam the jet fighter's IFF (Identification Friend or Foe) system, can cause this kind of episode. So if we talk about human errors, we should ask what caused those errors. Or maybe someone forgot to drive the IFF codes to the computers that control the AA systems. 

The jammer systems that deny the IFF system to transmit their codes to AA radars can cause situations where their air defense shoots aircraft down. Modern jet fighters and attack aircraft have only a couple of minutes or seconds to react when they see unknown, maybe hostile aircraft. If the aircraft comes closer to the headquarters would be an enemy attack aircraft, like the Ukrainian MiG-29 armed with "Storm Shadow" missiles, that aircraft could destroy the headquarters. 

One version of how to break the stealth technology is to use the IFF systems as the target.  AA crew can aim antiradiation missiles at the IFF system. Those radio transmitters are one vulnerability in stealth aircraft. 



The IFF system is a problematic part of the aircraft. The radio signal, that the IFF system sends makes aircraft vulnerable against the radar-homing missiles. Jammer systems that send radio signals to deny radar- or radio communication are vulnerable against antiradiation missiles. This means there are always new systems under development. 

Electronic warfare is becoming more important in modern battlefields. The drone systems require communication. And if the system can jam GPS and data communication. That makes it harder to use drones and communicate with troops. Also, jammers can deny the drone swarms internal communication. The jammer systems can be the target for HARM-type missiles created to destroy ECM systems and other radio transmitters. 

The stealth is the ultimate tool. But the next generation of radars and surveillance systems are hacking the stealth. The CCD cameras and lidar systems are making old-fashioned stealth useless. Same way next-generation AA radars might use pressure waves and other non-direct observation methods to uncover the stealth. The pressure waves around the aircraft are possible to detect by using AI-controlled systems that connect the data from multiple sources. 

And the weapon development is the race between the ultimate attacker and ultimate defender. The next-generation IFF systems might also use AI-based radar systems. The radar sends the identification request to the IFF system that answers that request. Then the AI starts to follow the aircraft that closes the IFF. And if it loses the target it can ask for identification again. That thing minimizes the need to send radio signals all the time. That helps stealth planes to complete their mission and makes them harder targets for enemy missiles.
