¿Se puede diagnosticar Parkinson a través de la escritura de un bolígrafo con IA?

El diagnóstico de la enfermedad de Parkinson sigue siendo un desafío en el ámbito médico. Su identificación depende de la observación de síntomas motores como temblores y rigidez, pero eso implica que se necesiten especialistas experimentados.
Frente a esas dificultades, un grupo de investigadores de la Universidad de California, Los Ángeles (UCLA), en los Estados Unidos, desarrolla un bolígrafo que podría servir en el futuro para hacer un diagnóstico de Parkinson.
Los resultados de su estudio fueron publicados en la revista Nature Chemical Engineering.
Utiliza una punta magnetoelástica y tinta de ferrofluido para convertir los movimientos de escritura de las personas en señales eléctricas verificables.
Gary Chen, doctorando y primer autor del estudio de la Universidad de California en Los Ángeles, Estados Unidos, afirmó: ”Los movimientos del bolígrafo generan fluctuaciones en el campo magnético traducidas en señales eléctricas”.
Consideró que el dispositivo podría alcanzar una alta precisión en la detección de la enfermedad gracias a la integración de redes neuronales avanzadas.
En diálogo con Infobae, el doctor Marcelo Merello, jefe del servicio de Movimientos Anormales de Fleni e investigador en ciencias médicas del Conicet, comentó tras leer el estudio publicado: “El desarrollo del bolígrafo para Parkinson aún está en su etapa inicial”.
Añadió: “Se necesitarán más investigaciones con un mayor número de participantes para evaluar si el dispositivo tiene eficacia y seguridad para el diagnóstico de la enfermedad”.

En la enfermedad de Parkinson, algunas neuronas del cerebro se degradan o mueren progresivamente. Por eso, los síntomas de la enfermedad son causados por la pérdida de neuronas que producen un neurotransmisor en el cerebro. Este mensajero se llama dopamina.
El Parkinson es el segundo trastorno neurodegenerativa más común después de la enfermedad de Alzheimer. Afecta a casi 10 millones de personas globalmente.
Sus síntomas, como temblores y rigidez, influyen drásticamente en la calidad de vida de quienes la padecen. Sin embargo, existen dificultades en su diagnóstico. En este complejo panorama es donde la innovación del bolígrafo en desarrollo podría jugar un rol crucial.

Este dispositivo no solo reduciría la necesidad de especialistas en escenarios de recursos limitados, sino que también mejoría la eficiencia del proceso diagnóstico, según los científicos liderados por Jun Chen.
El dispositivo se centra en los patrones motores que marca la escritura. Los usa como biomarcador digital.
La aplicación de inteligencia artificial en el análisis de esas señales añade un nivel extra de fiabilidad y precisión a esta técnica pionera.

El bolígrafo emplea sofisticadas técnicas científicas e innovaciones tecnológicas. La unión de una punta flexible de silicona Ecoflex y tinta de ferrofluidos permite registrar movimientos generadores de variaciones en el flujo magnético.
”Este mecanismo captura estos movimientos en señales eléctricas de alta fidelidad”, según escribieron los investigadores en el trabajo.
Una característica notable del bolígrafo es que no requiere una fuente de energía externa. A través de la interacción entre la tinta y la punta, se obtiene un flujo continuo de datos en tiempo real y se visibiliza un análisis inmediato y acertado.
Las señales captadas se procesan por medio de la llamada «red neuronal convolucional», que es capaz de identificar patrones complejos.

Esto posibilita distinguir entre la escritura de pacientes con Parkinson y personas sanas. Logra una precisión superior al 95%.
Para evaluarlo, los investigadores reclutaron a 16 personas. Tres de ellos eran pacientes que ya tenían el diagnóstico de Parkinson. Los otros 13 participantes no tenían la enfermedad.
Los participantes realizaron tareas fáciles de escritura como el dibujo de líneas onduladas para asegurarse de que no hubiera complicaciones para las personas con dificultades de lectura o hablantes no nativos.

Los desarrolladores postularon que el bolígrafo es rentable y apto para producción masiva. Las características de los materiales que lo forman aseguran su eficacia en diversos entornos.
Además, permite transferir los datos recopilados a dispositivos electrónicos para análisis minucioso y seguimiento constante. Esto permitiría que se pueda usar en diferentes entornos clínicos.

A pesar del éxito inicial, los autores reconocieron ciertas limitaciones en su estudio. Mencionaron que las pruebas se llevaron a cabo con solo 16 participantes, lo que restringe la posibilidad de generalizar los resultados.
”Nuestra investigación inicial tiene limitaciones debido al reducido número de participantes”, recalcó Chen.
Esperan sumarle más funcionalidades como sincronización inalámbrica y almacenamiento basado en la nube, llevar a cabo estudios con grupos de participantes más grandes y diversos, y evaluar el desempeño del bolígrafo en casos de que la mano no dominante esté afectada por Parkinson.

Texas AG investigates Beto O’Rourke PAC over support for quorum-breaking lawmakers

NEWYou can now listen to Fox News articles!
Texas Attorney General Ken Paxton is looking into two political action committees for allegedly violating the law by assisting Texas state Democrats’ travel out of the state in an effort to avoid a quorum during a redistricting standoff.
The groups are the Powered by People PAC, led by former Rep. Beto O’Rourke, and the Texas Majority PAC, led by members of his former staff.
«Any Democrat coward breaking the law by taking a Beto Bribe will be held accountable,» Paxton said in a news release on Wednesday.
O’Rourke unsuccessfully sought the Democratic presidential nomination in 2020, lost to Sen. Ted Cruz in a closely-watched 2018 contest, and lost to Gov. Greg Abbott in 2022. Still, he remains a prominent voice in the state’s political scene.

«Texas cannot be bought. I look forward to thoroughly reviewing all of the documents and communications obtained throughout this investigation. These jet-setting runaways have already lost public trust by abandoning our state, and Texans deserve to know if they received illegal bribes to do it,» Paxton continued.
Public records indicated that the Powered by People PAC does get a significant number of smaller donations through individuals by platforms like ActBlue, but it’s also received over hundreds of thousands from the progressive consulting firm Middle Seat, and $100,000 from Simone Coxe, a nonprofit leader who was a major funder of O’Rourke’s gubernatorial bid, according to the Texas Tribune. In addition, FEC records show that the Harris Victory Fund gave over $114,000 in January 2024 and $60,000 in December 2023.
In 2024, it also received just over $5,000 from Luci Baines Johnson, the former first daughter of President Lyndon Johnson.

According to the Texas Tribune, the PAC has acknowledged assisting lawmakers with travel outside of the state, including helping to cover $500 daily fines.
«100% of your donation will go to supporting Texas Democrats in their fight against Trump’s power grab,» the website stated, Fox News Digital previously reported.
The group reports over $3.5 million in cash on hand as of June 30, according to Federal Election Commission records.

As for the Texas Majority PAC, it receives heavy funding from George Soros, a longtime Democratic donor.
«If Texas lawmakers are bowing to the Soros Slush Fund rather than the will of the voters, Texans deserve to know. Getting financial payouts under the table to abandon your legislative duties is bribery,» Paxton said in a Thursday statement. «Texas Majority PAC’s actions seem to indicate that it may be using its Soros-funded resources to break the law and fund the illegal abandonment of public office. If that’s the case as determined by this investigation, there will be a heavy price to pay.»

Fox News Digital reached out to Powered by People PAC and the Texas Majority PAC for comment on the Paxton investigation. O’Rourke responded to a post from Paxton on Wednesday, saying the Democrat is «scared of accountability.»
«Scared? If we stop the Texas steal & win the House, your guy’s crimes & corruption will be exposed for all to see. The girls traded with Epstein. The bribes taken from foreign governments. And when he goes down, your corrupt, impeached, twice indicted ass is going down with him!» O’Rourke replied on X.

WATCH: GOP senators divided over whether Epstein documents are a distraction or a needed reckoning

NEWYou can now listen to Fox News articles!
Republican senators offered a range of responses when pressed on how the Trump administration has been handling the Epstein files controversy, with some calling it a distraction and others arguing the American people are «entitled» to answers.
Attorney General Pam Bondi announced the «first phase» of declassified files related to Jeffrey Epstein Feb. 27, noting the move was following through on President Donald Trump’s commitment to «lifting the veil» on Epstein and his co-conspirator’s actions. Bondi also said the same month she was in possession of an Epstein «client list.»
However, the February declassification contained mostly information and files that had already been publicly available, and the Justice Department subsequently indicated that no «client list» exists. Since then, a series of events, including a clash between FBI Deputy Director Dan Bongino and Attorney General Bondi, have led to mounting pressure on the Trump administration to release more files.
‘NOT GOING AWAY’: INSIDE THE EPSTEIN DRAMA THAT’S THROWN HOUSE GOP INTO CHAOS

«This is factual. Epstein trafficked a lot of young women, some of whom were minors. The American people are entitled to know who — if anyone — he trafficked these young women to, besides himself, and why they weren’t prosecuted,» John Kennedy, R-La., said.
«Now that’s a very simple question that’s at the bottom of all of this. The Department of Justice is going to have to answer that question to the satisfaction of the American people.»
TABLES TURN AS HOUSE GOP BLASTS DEMS FOR SUDDENLY DEMANDING EPSTEIN TRANSPARENCY FROM TRUMP ADMIN
Kennedy’s call for transparency comes after the president described the Epstein situation as a «hoax» while blasting Democrats and other «weaklings» who continue to buy into it.
«Their new SCAM is what we will forever call the Jeffrey Epstein Hoax, and my PAST supporters have bought into this ‘bull—-,’ hook, line, and sinker,» Trump wrote on his Truth Social platform last month amid mounting reports of internal division within the administration over its handling of the Epstein case
When asked about how the Trump administration was handling the Epstein furor, Sen. Markwayne Mullin, R-Okla., said he thought the situation was being used by Democrats to create a «distraction» from the ongoing investigations into former President Biden and others, like the probe related to Biden’s use of an autopen tool to sign important documents and the investigation into whether Obama-era officials manufactured evidence to accuse Trump of Russian collusion.

«Look what’s being investigated right now through the Biden administration. … So, what are they going to talk about now?» Mullin asked. «This is nothing but a distraction from the actual facts that is coming out about the Biden administration. Of course, the Democrats say, ‘Well, we’re just about transparency.’ Well, where was the transparency the last four years?»
Democrats have suggested Trump could be implicated in the files, but Mullin said that if such a circumstance were true, the information would have been leaked by the Biden administration.
Mullin’s counterpart in the Senate, Republican Oklahoma Sen. James Lankford took more of a middle ground in his response about how the administration has been handling the Epstein files.

«The challenge is there are people that are victims that are in it, and there are folks that are not criminals that are in it as well,» Lankford said. «And the challenge the Department of Justice has is you’ve got a girl that was 14, 16 years old and was abused. Well, now she’s, let’s say 26 or 30, married and has children.
«Maybe her family knows about this, maybe they don’t. I don’t know the situation, but we gotta figure out a way to be able to protect those folks that are genuine victims on all this as well as getting out as much information as you possibly can.»
For Sen. Susan Collins, R-Maine, the debate about the Epstein files was not something she was interested in talking about when approached by Fox News Digital.
«I’m going,» Collins responded when pressed on the matter outside the Capitol complex.
