| Business and Basis of Presentation | Business and Basis of Presentation Our Business-An Overview NeuroMetrix, Inc., or the Company, is a commercial stage, innovation driven healthcare company combining neurostimulation and digital medicine to address chronic health conditions including chronic pain, sleep disorders, and diabetes. The Company has two primary products. Quell is an over-the-counter wearable therapeutic device for chronic pain. DPNCheck® is a rapid point-of-care test for diabetic neuropathy which is the most common long-term complication of Type 2 diabetes. In June 2019 the Company announced a business restructuring aimed at operating costs and cash preservation while continuing to focus on supporting its DPNCheck® product line, managing its existing Quell® business while evaluating alternative therapeutic applications for the core technology, maintaining its strategic collaboration with GlaxoSmithKline, and attempting to negotiate a settlement of the previously disclosed and ongoing Federal Trade Commission (FTC) investigation which is centered on Quell advertising. The restructuring involved a reduction in force, a planned consolidation of all operations in a single location, and the write-down of excess Quell inventory. In connection with the restructuring, the Company recorded in the second quarter of 2019 a restructuring charge of $2.3 million (See Note 7.). It is likely that the Company will incur future charges associated with settlement of the FTC matter; however, the amount of such charges cannot be reasonably estimated at this time (See Note 8.). In June 2019, the Company also announced that it had retained an investment bank to explore strategic alternatives to enhance shareholder value, including the potential sale or merger of the Company. The accompanying financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has suffered recurring losses from operations and negative cash flows from operating activities. At June 30, 2019, the Company had an accumulated deficit of $192.3 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for the one-year period from the date of issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company held cash and cash equivalents of $5.0 million as of June 30, 2019. The Company believes that these resources, future GSK collaboration milestone payments, and the cash to be generated from future product sales will be sufficient to meet its projected operating requirements through 2019. Accordingly, the Company will need to raise additional funds to support its operating and capital needs in 2020. The Company continues to face significant challenges and uncertainties and, as a result, the Company’s available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of the Company’s products and the uncertainty of future revenues from new products; (b) changes the Company may make to the business that affect ongoing operating expenses; (c) changes the Company may make in its business strategy; (d) regulatory developments affecting the Company’s existing products; (e) changes the Company may make in its research and development spending plans; (f) delays in the anticipated timing of achievement of GSK milestones; (g) the final outcome of the FTC civil investigative demand enforcement action involving Quell; and (h) other items affecting the Company’s forecasted level of expenditures and use of cash resources. The Company may attempt to obtain additional funding through achievement of milestones under the GSK collaboration, public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, the Company may not be able to secure such funding in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity or debt securities to raise additional funds, its existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of its sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occurs, the Company’s ability to achieve its development and commercialization goals would be adversely affected. Unaudited Interim Financial Statements The accompanying unaudited balance sheet as of June 30, 2019, unaudited statements of operations for the quarters and six months ended June 30, 2019 and 2018, unaudited statements of changes in stockholders' equity for the six months ended June 30, 2019 and 2018 and the unaudited statements of cash flows for the six months ended June 30, 2019 and 2018 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. The accompanying balance sheet as of December 31, 2018 has been derived from audited financial statements prepared at that date, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 24, 2019 (File No. 001-33351), or the Company’s 2018 Form 10-K. Revenues Revenues include product sales, net of estimated returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for product transferred. Revenue is recognized when contractual performance obligations have been satisfied and control of the product has been transferred to the customer. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. Accounts receivable are recorded net of the allowance for doubtful accounts which represents the Company’s best estimate of credit losses. Allowance for doubtful accounts was $25,000 as of June 30, 2019 and December 31, 2018. Two customers accounted for 31% and one customer accounted for 20% of total revenues in the quarters and six months ended June 30, 2019, respectively. Two customers accounted for 24% and 29% of total revenues in the quarters and six months ended June 30, 2018, respectively. Three customers accounted for 62% and two customers accounted for 45% of accounts receivable as of June 30, 2019 and December 31, 2018, respectively. Collaboration income Collaboration income is recognized within Other income when contractual performance obligations, outside the ordinary activities of the Company, have been satisfied and control has been transferred to a collaboration partner. Collaboration income for each performance obligation is based on the fair value of such performance obligation relative to the total fair value of all performance obligations multiplied by the overall transaction price. A deferred collaboration income liability is recorded when payments are received prior to satisfaction of performance obligations. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of $7,116,667 and $8,505,704, for the six months ended June 30, 2019 and 2018, respectively. Stock-based Compensation Total compensation cost related to non-vested awards not yet recognized at June 30, 2019 was $139,588. The total compensation costs are expected to be recognized over a weighted-average period of 1.3 years. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 required that lessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The Company adopted ASU 2016-02, using the modified retrospective method, upon its effective date of January 1, 2019. The impact of adoption was an increase to long-term assets and total liabilities of approximately $1.9 million as of January 1, 2019. The following table summarizes the effects of adopting ASU 2016-02 on the Company's balance sheet as of June 30, 2019:
The following table summarizes the effects of adopting ASU 2016-02 on the Company's balance sheet as of December 31, 2018:
Adoption of ASU 2016-02 had no impact on the Company's statements of operations, statements of changes in stockholders' equity and statements of cash flows. |

| Credit Facility | Credit Facility The Company is party to a Loan and Security Agreement, as amended (the “Credit Facility”), with a bank. As of June 30, 2019, the Credit Facility permitted the Company to borrow up to $2.5 million on a revolving basis. The Credit Facility was amended most recently in June 2019 and expires in September 2019. Amounts borrowed under the Credit Facility will bear interest equal to the prime rate plus 0.5%. Any borrowings under the Credit Facility will be collateralized by the Company’s cash, accounts receivable, inventory, and equipment. The Credit Facility includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by the Company. As of June 30, 2019, the Company was in compliance with these covenants and had not borrowed any funds under the Credit Facility. However, $226,731 of the amount under the Credit Facility is restricted to support letters of credit issued in favor of the Company's landlords. Consequently, the amount available for borrowing under the Credit Facility as of June 30, 2019 was approximately $2.3 million. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies Disclosure [Text Block] | Contingencies As previously disclosed, in 2017, the Company received a Civil Investigative Demand (“CID”) from the Federal Trade Commission (the “FTC”). The CID requested information in connection with an FTC review for compliance of the Company’s advertising about its product Quell with Sections 5 and 12 of the Federal Trade Commission Act (the “FTC Act”). During 2017 and 2018, the Company provided responses to those requests. The Company met with the staff of the FTC (the “Staff”) on three occasions between March and July 2019 to discuss the Company’s responses to FTC inquiries, and the Company has provided additional information in response to further requests from the FTC. As part of those discussions, the parties are engaged in a dialogue regarding the possible structuring of a settlement of this matter, which is likely to include a monetary judgment that would be payable to the FTC. The Company and the FTC will also be negotiating the scope and terms of a proposed consent order (the “Order”), which is expected to prohibit the Company from making certain claims in the Company’s advertising about Quell, as will likely be defined by the Order. The Company is currently awaiting feedback from the Staff on the latest discussions and responses to Staff inquiries, and intends to continue the dialogue with the Staff regarding a resolution of this matter. The ultimate outcome cannot be reasonably estimated at this time; however, the Company believes that a material financial loss is probable. |

Total recorded rent expense was $332,049 and $307,420, for the six months ended June 30, 2019 and 2018, respectively. The Company records rent expense on its facility leases on a straight-line basis over the lease term. |

| Share-based Payment Arrangement [Policy Text Block] | Stock-based Compensation Total compensation cost related to non-vested awards not yet recognized at June 30, 2019 was $139,588. The total compensation costs are expected to be recognized over a weighted-average period of 1.3 years. |

| Our Business-An Overview | Our Business-An Overview NeuroMetrix, Inc., or the Company, is a commercial stage, innovation driven healthcare company combining neurostimulation and digital medicine to address chronic health conditions including chronic pain, sleep disorders, and diabetes. The Company has two primary products. Quell is an over-the-counter wearable therapeutic device for chronic pain. DPNCheck® is a rapid point-of-care test for diabetic neuropathy which is the most common long-term complication of Type 2 diabetes. In June 2019 the Company announced a business restructuring aimed at operating costs and cash preservation while continuing to focus on supporting its DPNCheck® product line, managing its existing Quell® business while evaluating alternative therapeutic applications for the core technology, maintaining its strategic collaboration with GlaxoSmithKline, and attempting to negotiate a settlement of the previously disclosed and ongoing Federal Trade Commission (FTC) investigation which is centered on Quell advertising. The restructuring involved a reduction in force, a planned consolidation of all operations in a single location, and the write-down of excess Quell inventory. In connection with the restructuring, the Company recorded in the second quarter of 2019 a restructuring charge of $2.3 million (See Note 7.). It is likely that the Company will incur future charges associated with settlement of the FTC matter; however, the amount of such charges cannot be reasonably estimated at this time (See Note 8.). In June 2019, the Company also announced that it had retained an investment bank to explore strategic alternatives to enhance shareholder value, including the potential sale or merger of the Company. The accompanying financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has suffered recurring losses from operations and negative cash flows from operating activities. At June 30, 2019, the Company had an accumulated deficit of $192.3 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for the one-year period from the date of issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company held cash and cash equivalents of $5.0 million as of June 30, 2019. The Company believes that these resources, future GSK collaboration milestone payments, and the cash to be generated from future product sales will be sufficient to meet its projected operating requirements through 2019. Accordingly, the Company will need to raise additional funds to support its operating and capital needs in 2020. The Company continues to face significant challenges and uncertainties and, as a result, the Company’s available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of the Company’s products and the uncertainty of future revenues from new products; (b) changes the Company may make to the business that affect ongoing operating expenses; (c) changes the Company may make in its business strategy; (d) regulatory developments affecting the Company’s existing products; (e) changes the Company may make in its research and development spending plans; (f) delays in the anticipated timing of achievement of GSK milestones; (g) the final outcome of the FTC civil investigative demand enforcement action involving Quell; and (h) other items affecting the Company’s forecasted level of expenditures and use of cash resources. The Company may attempt to obtain additional funding through achievement of milestones under the GSK collaboration, public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, the Company may not be able to secure such funding in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity or debt securities to raise additional funds, its existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of its sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occurs, the Company’s ability to achieve its development and commercialization goals would be adversely affected. |

The accompanying balance sheet as of December 31, 2018 has been derived from audited financial statements prepared at that date, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 24, 2019 (File No. 001-33351), or the Company’s 2018 Form 10-K. |

| Revenues | Revenues Revenues include product sales, net of estimated returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for product transferred. Revenue is recognized when contractual performance obligations have been satisfied and control of the product has been transferred to the customer. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. Accounts receivable are recorded net of the allowance for doubtful accounts which represents the Company’s best estimate of credit losses. Allowance for doubtful accounts was $25,000 as of June 30, 2019 and December 31, 2018. Two customers accounted for 31% and one customer accounted for 20% of total revenues in the quarters and six months ended June 30, 2019, respectively. Two customers accounted for 24% and 29% of total revenues in the quarters and six months ended June 30, 2018, respectively. Three customers accounted for 62% and two customers accounted for 45% of accounts receivable as of June 30, 2019 and December 31, 2018, respectively. Collaboration income Collaboration income is recognized within Other income when contractual performance obligations, outside the ordinary activities of the Company, have been satisfied and control has been transferred to a collaboration partner. Collaboration income for each performance obligation is based on the fair value of such performance obligation relative to the total fair value of all performance obligations multiplied by the overall transaction price. A deferred collaboration income liability is recorded when payments are received prior to satisfaction of performance obligations. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of $7,116,667 and $8,505,704, for the six months ended June 30, 2019 and 2018, respectively. |

| Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 required that lessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The Company adopted ASU 2016-02, using the modified retrospective method, upon its effective date of January 1, 2019. The impact of adoption was an increase to long-term assets and total liabilities of approximately $1.9 million as of January 1, 2019. The following table summarizes the effects of adopting ASU 2016-02 on the Company's balance sheet as of June 30, 2019:
The following table summarizes the effects of adopting ASU 2016-02 on the Company's balance sheet as of December 31, 2018:
Adoption of ASU 2016-02 had no impact on the Company's statements of operations, statements of changes in stockholders' equity and statements of cash flows. |
