* Preserved precentral gyrus assessed using CT.
* Suitable vascular anatomy assessed using CT venography.
* Suitable anatomy for subcutaneous pocket creation.
* Able to undergo anesthesia.
* Willing and able to comply with all investigational requirements, including clinical testing visits and training visits in the home.

* Diagnosis of ALS-FTD or another dementia.
* Active implanted device (e.g., deep brain stimulator, cardiac defibrillator, pacemaker, vagal nerve stimulator, spinal cord stimulator, diaphragmatic pacer, etc.).
* Known allergy to patient-contacting materials included in the implanted device.
* Contraindication to angiographic imaging or iodine contrast media.
* History of central venous sinus thrombosis.
* Recent history of new venous thromboembolic event (in the 6 months prior to implant), recurrent history of venous thromboembolic disease, or hypercoagulable state.
* Contraindication to antithrombotic therapy.
* Participant is at substantially increased risk of infection, including immunocompromised status, recurrent or chronic infection, or poorly controlled diabetes mellitus.
* Significant risk of non-healing of the subcutaneous pocket incision, including history of chronic non-healing surgical wounds or poorly controlled diabetes mellitus.
* Pregnant or breast feeding.
* Patients who are currently enrolled in any other clinical trial that would confound interpretation of safety or effectiveness data or may interfere with the ability to meet study requirements.
* Any other disease or disorder that could significantly affect participation in the study. Examples may include corrected vision insufficient for viewing computer screens or hearing insufficient for following verbal instructions, which might impact the participant's ability to participate in BCI training and testing.
