Brain-Computer Interface: How an FDA 'Breakthrough Tag' could expedite voice to the mute
The speech restoration device—an AI-driven brain-machine interface designed to assist individuals with severe speech impairments caused by conditions such as stroke, spinal cord injury, amyotrophic lateral sclerosis (ALS), cerebral palsy, and multiple sclerosis—represents a true revolution in healthcare.
Although it was a high-risk endeavor for Noland Arbaugh and Brad Smith when Neuralink, the neurotechnology company founded by Elon Musk in 2016, conducted its human trials of this technology in recent years, the prospect of this technology becoming a widely accessible, high-tech therapy for thousands with speech impairments may not be far off.
Neuralink recently reached a major milestone in its mission to transform healthcare. Last week, the company announced that its speech restoration device had received the US Food and Drug Administration's (FDA) "Breakthrough Device" designation. This recognition, granted under the FDA's Breakthrough Devices Program, is intended to expedite the development and review of medical technologies that offer significant improvements over existing treatments for life-threatening or irreversibly debilitating conditions.
Here's a detailed look at the brain implant's potential to help individuals with severe speech impairments:
What Is A Breakthrough Device
The FDA's Breakthrough Devices Program is designed to expedite the development, assessment, and review of medical devices that can provide significant improvements over current treatment options. The goal is to offer patients and healthcare providers faster access to innovations that could meaningfully improve health outcomes. By granting this designation to Neuralink's speech restoration device, the FDA aims to accelerate the device's journey toward becoming a clinically available treatment for individuals with severe neurological conditions.
This speech restoration device has been specifically designed to assist individuals suffering from severe speech impairments caused by neurological conditions. These conditions include amyotrophic lateral sclerosis (ALS), stroke, spinal cord injury, cerebral palsy, multiple sclerosis, and other disorders that impact the brain's ability to control speech. For individuals with these conditions, communication can become incredibly difficult, severely limiting their quality of life. The speech restoration device seeks to restore communication abilities by utilizing a brain-computer interface (BCI) that allows users to communicate through neural signals.
The Revolution that Neuralink Technology offers:
Currently there are three key BCI driven healthcare solutions that Neuralink has designed and developed.
N1 Implant:
At the heart of Neuralink's mission is its N1 implant, a small, coin-sized device designed to be implanted in the brain. Equipped with flexible threads containing electrodes, the N1 implant can detect neural activity and transmit these signals to external devices. This allows for direct communication between the brain and the device, bypassing damaged pathways in the brain and nervous system. The device is implanted using a robotic surgical system designed to minimize invasiveness and maximize precision. This technology is central not only to speech restoration but also to other treatments that Neuralink is exploring for neurological conditions.
Blindsight:
Another groundbreaking product from Neuralink is Blindsight, an experimental device aimed at restoring vision in individuals with total visual impairment. Instead of relying on the optic nerve, Blindsight directly stimulates the visual cortex of the brain, bypassing damaged pathways and enabling the brain to create a visual perception. The FDA has also granted Breakthrough Device Designation to Blindsight, highlighting its potential to change the lives of individuals who have lost their sight due to optic nerve damage.
Speech Restoration Device:
The speech restoration device, which earned FDA's Breakthrough Device Designation, is the latest in Neuralink's portfolio. This device aims to assist individuals with speech impairments due to various neurological disorders. The device's development underscores the company's commitment to improving the lives of individuals affected by debilitating conditions.
Clinical Applications and Trials: A New Era in Neurological Care
Neuralink has been actively testing its devices in human clinical trials. In January 2024, Noland Arbaugh became the first human recipient of a Neuralink implant. While the device faced some challenges, including the retraction of implant threads, it enabled Arbaugh to control a computer cursor with his thoughts, demonstrating the potential for BCIs to restore digital autonomy to individuals with paralysis.
In April 2025, Brad Smith, a man paralysed by ALS, became the third recipient of a Neuralink implant. Smith's ability to use the device to type, edit videos, and communicate through brain-controlled cursor movements marked a significant leap forward in restoring the ability to communicate for individuals with severe neurological impairments. This success story illustrates how BCIs can dramatically improve the quality of life for people with disabilities, giving them a voice when traditional methods of communication are no longer viable.
Ethical Considerations and Challenges
As promising as Neuralink's technology is, it raises a host of ethical and technical questions. Some of the most pressing concerns include:

Tuna salad recalled in US: Listeria alert hits 7 states; full list of affected regions
Represntational AI image Grocery stores across seven US states have pulled tuna salad items off their shelves after fears of listeria contamination. The recall, announced by the US food and drug administration (FDA) on Monday, was linked to products supplied by Reser's Fine Foods. The contamination was traced to breadcrumbs used in the tuna salads. No cases of illness have been reported so far. The affected items include sandwiches, croissants, snack packs and salad trays sold in Jewel-Osco outlets in Illinois, Indiana and Iowa, and in Albertsons, Randalls and Tom Thumb stores in Arkansas, Louisiana, Oklahoma and Texas. All the products have specific sell-by dates between 16 and 19 July. Customers have been advised to throw away or return recalled items for a full refund.

5 effective tips for Indian women to reduce hair fall immediately
Hair fall is quickly becoming a major concern among Indian women that is made worse by pollution, hard water, stress, hormonal imbalances and heat-styling. In an interview with HT Lifestyle, Dr Stuti Khare Shukla, MD Dermatologist, Founder of Elements of Aesthetics and Founder of FDA-approved hair growth booster, shared, 'Latter hair shedding is abnormal and it generally requires urgent attention if it is sudden or excessive (50 – 100 daily). Having worked as a dermatologist and helped thousands to fight against hair loss, I am a believer in early intervention with either natural or science based means and can be effective.' A top dermatologist shares the secret to stopping hair loss in Indian women before it is too late.(Image by Freepik) Here's what she suggests you do: 1. Switch to sulphate-free and paraben-free shampoos Use organic products: Opt for sulphate and paraben free products on your hair. Many shampoos in the market contain sodium lauryl sulphate which can make the hair very dry. Be very gentle while massaging the scalp while shampooing since your hair is the weakest when wet.(Unsplash) There are plenty of commercial shampoos that contain harsh chemicals such as sulphates (SLS) and parabens that remove natural oils from your scalp, giving the hair a dry and brittle feel. Select soothing dermatologically tested shampoos that clean but do not strip your scalp barrier. Search for recipes that contain ingredients such as biotin, keratin, or caffeine that help in strengthening and volumising hairs. 2. Nourish from within: Focus on nutrition Nutritional guide for healthy hair: Foods to boost growth and prevent shedding. (Freepik) Lack of essential nutrients is perhaps the most under looked hair fall cause. Indian women including vegetarians may have deficiencies of Vitamin B12, iron and protein. Introduce leafy greens, dairy, lentils, eggs and nuts to your diet in your meals. You can also think about the supplements under doctor's guidance to even out deficiencies and promote hair regrowth. Do blood tests like thyroid profile, vitamin B12, prolactin, dihydrotestosterone, and iron profile on a regular basis. If you experience delayed periods, make sure to get checked for PCOS. Also, include good supplements in your diet, such as a combination of hair nutraceuticals, multivitamins and IRID supplements. 3. Avoid heat styling and restrain harsh hair treatments Frequent heat styling and tight hairstyles can weaken the hair shaft and damage follicles, leading to breakage and traction alopecia. Use heat protectants, loosen your hairstyles, and give your scalp breaks. (Freepik) Hair strands can be seriously destroyed by constant bouts of employing straighteners, curling irons and blow dryers. Likewise, a chemical treatment such as rebonding and colouring weakens the hair shaft. Give your hair consistent time off from styling habits and ensure the use of a heat product when it is necessary. Go natural with your hairs and avoid tight hairstyles that pull on the roots. 4. Manage stress and prioritise sleep A regular sleep pattern contributes to the formation of melatonin required for hair growth. We should fix our sleep pattern and get good 7-8 hours of sleep every day.(Unsplash) With high pressure, the body releases Cortisol, a hormone that causes disruption in the hair growth cycle. Simple things such as deep breathing, yoga, journaling, or moving around with a brisk walk can go a long way in taking care of your mental state and indeed your hair health. Enough sleep (7 to 8 hours) is equally necessary for the scalp and hormonal balance. 5. Stay hydrated for healthy hair roots Drinking enough water can help you detoxify, boost digestion, improve the quality of your skin and hair and help you feel well-balanced. (Shutterstock) Even though many do not appreciate the role of hydration in preventing hair fall, water facilitates circulations of nutrients to the hair follicles. When the body is dehydrated, it factors out other organs and holds water for the vital organs, leaving very little hydration for the scalp. At least 8 – 10 glasses of water consumed each day is helpful for healthy roots of the hair.
