Clinical assessment will be done at screen/baseline, 3th course and 6th course. The specific aims are to compare lipoic acid versus control on: motor function and disease progression. During the study period, clinical effect index will be recorded, including bulbar function, motor function, respiratory function, and safety index including blood and urine routine, liver and kidney function, coagulation function.
This project adds to non-invasive BCIs for communication for adults with severe speech and physical impairments due to neurodegenerative diseases. Researchers will optimize & adapt BCI signal acquisition, signal processing, natural language processing, & clinical implementation. BCI-FIT relies on active inference and transfer learning to customize a completely adaptive intent estimation classifier to each user's multi-modality signals simultaneously. 3 specific aims are: 1. develop & evaluate methods for on-line & robust adaptation of multi-modal signal models to infer user intent; 2. develop & evaluate methods for efficient user intent inference through active querying, and 3. integrate partner & environment-supported language interaction & letter/word supplementation as input modality. The same 4 dependent variables are measured in each SA: typing speed, typing accuracy, information transfer rate (ITR), & user experience (UX) feedback. Four alternating-treatments single case experimental research designs will test hypotheses about optimizing user performance and technology performance for each aim.Tasks include copy-spelling with BCI-FIT to explore the effects of multi-modal access method configurations (SA1.3a), adaptive signal modeling (SA1.3b), & active querying (SA2.2), and story retell to examine the effects of language model enhancements. Five people with SSPI will be recruited for each study. Control participants will be recruited for experiments in SA2.2 and SA3.4. Study hypotheses are: (SA1.3a) A customized BCI-FIT configuration based on multi-modal input will improve typing accuracy on a copy-spelling task compared to the standard P300 matrix speller. (SA1.3b) Adaptive signal modeling will allow people with SSPI to typing accurately during a copy-spelling task with BCI-FIT without training a new model before each use. (SA2.2) Either of two methods of adaptive querying will improve BCI-FIT typing accuracy for users with mediocre AUC scores. (SA3.4) Language model enhancements, including a combination of partner and environmental input and word completion during typing, will improve typing performance with BCI-FIT, as measured by ITR during a story-retell task. Optimized recommendations for a multi-modal BCI for each end user will be established, based on an innovative combination of clinical expertise, user feedback, customized multi-modal sensor fusion, and reinforcement learning.

Amyotrophic Lateral Sclerosis, also known as Charcot disease, is a neurodegenerative disease evidenced by gradual paralysis of the muscles involved in voluntary motor function. The clinical hallmark of Amyotrophic Lateral Sclerosis is the combination of upper and lower motor neuron signs and symptoms. The most recent studies suggest that up to 50% of Amyotrophic Lateral Sclerosis patients demonstrate mild to moderate cognitive disturbance. Impaired social cognition, including a deficit in the recognition of facial emotions and the identification of vocal prosody, is recognized as a part of the cognitive phenotype of Amyotrophic Lateral Sclerosis, with crucial implications for patients' and caregivers' training. However, studies remain scarce and the data acquired must be supported. The evolution of these manifestations during the disease is still poorly understood. In this study the investigators aim to assess the social cognition capacities of patients with Amyotrophic Lateral Sclerosis compared to healthy matched control subjects.
Background: Amyotrophic lateral sclerosis type 4 (ALS4) is an inherited motor neuron disease. People with ALS4 have a change in the amount of RNA and DNA that bind together. This binding of RNA with DNA forms units called R-loops. Researchers want to learn how R-loops are related to ALS4. To do this, they will study people with inherited neurological conditions that may affect R-loop levels. These include ALS4, progressive external opthalmoplegia with mitochondrial deletions (PEOB2), Aicardi-Goutieres syndrome (AGS), and ataxia and oculomotor apraxia type 2 (AOA2). Objective: To learn how the binding of RNA with DNA (R-loops) is related to neurological disease. Eligibility: People age 5 and older with ALS4, PEOB2, AGS, and AOA2. Healthy relatives and nonrelatives are also needed. Design: Participants may be screened with a review of x-rays and other medical records. Healthy relative and nonrelative participants will have 1 visit. All other participants will have 4 visits over 3 years. At visits, participants will undergo some or all of the following: Medical history Physical exam Tests of muscle strength and volume and physical function Blood tests Pregnancy test (for some females) Skin biopsy of forearm Magnetic resonance imaging (MRI) Dual x-ray absorptiometry (DEXA). Some tests are optional. The MRI uses a magnetic field and radio waves to take pictures. Participants will lie on a table that slides in and out of the scanner. The scanner makes noise. They will get earplugs. The DEXA scan uses x-rays to take pictures. MRI and DEXA will be used to measure muscle, fat, and lean body mass. ...
This study aims to evaluate safety and efficacy of tSMS in ALS patients and to obtain preliminary data about the effects of tSMS on cortical excitability. To this purpose, 40 ALS patients will be recruited and randomized to real or sham tSMS. After at least 3 months follow-up, they will undergo tSMS, daily for 120 min, at home, for 6 consecutive months. Clinical status will be tested before, during and after the stimulation period. Moreover, cortical excitability will be tested by transcranial magnetic stimulation (TMS) before and after the stimulation period.
"Brain-computer interfaces (BCIs) are computer-based systems that acquire brain signals, analyze them, and translate them into commands that are relayed to an output device to carry out a desired action. BCIs represent a very active and promising field of research among devices for people with severe motor disabilities. As the currently available systems correspond to research prototypes, they are not adapted to daily live situations. On the other hand, some systems have recently been commercialized, principally for video games but they are not satisfactory for use as a substitute technology in disability. A BCI's prototype for alternative communication using a virtual keyboard, the P300 Speller, has been developed by the National Institute for Research in Digital Science and Technology (Athena team - Nice University). This prototype includes an EEG-cap with gel based active electrodes. A recent study conducted on 20 patients with ALS (University Hospital, Nice) demonstrated the usability of the system and the patient satisfaction concerning the ease of use and utility. To achieve a system that can be used in daily live in severely disabled patients, technical developments are necessary. The investigators have conceptualized and developed an ergonomic, comfortable, headset, including dry electrodes to allow a prolonged use of the system. The purpose of the study conducted all along the development of the headset is to improve the developed system until a successful system is achieved. This study is a monocentric usability study conducted on ALS people.

A multi-center registration study of natural history and clinical characteristics of ALS in mainland China
MND-SMART is investigating whether selected drugs can slow down the progression of motor neurone disease (MND) and improve survival. The study is 'multi-arm' meaning more than one treatment will be tested at the same time. The trial started with 3 arms; drug 1 (memantine), drug 2 (trazodone) and placebo (dummy drug). A third drug, amantadine, was added in April 2023. The first two drugs, memantine and trazodone, were removed from the trial in September 2023 due to lack of benefit. The trial currently has 2 recruiting arms; amantadine and placebo. This allows the evaluation of each drug versus placebo. Participants will be randomly allocated to either of the recruiting arms. Medicines being tested are already approved for use in other conditions. MND-SMART has an 'adaptive' design. This means medicines being studied can change according to emerging results. Treatments shown to be ineffective can be dropped and new drugs can be added over the duration of the study. This will allow many treatments, over time, to be efficiently and definitively evaluated. The medicines being tested have been selected following a rigorous process involving a systematic, unbiased, and comprehensive review of past clinical trials data, as well as information from pre-clinical research (studies in laboratories), for MND and other related neurodegenerative disorders. Drugs have been ranked for inclusion in MND-SMART by a group of independent MND experts according to set criteria. These include consideration of how the drugs work, their safety profiles, and the quality of previous studies. New drugs will be selected for investigation in MND-SMART based on continuous review of constantly updated scientific evidence as well as findings from state-of-the-art human stem cell based drug discovery platforms. These can be added by substantial amendment to the protocol.
