Business Description and Basis of Presentation [Text Block] | 1. Business DiaMedica Therapeutics Inc. and its wholly-owned subsidiaries, DiaMedica USA, Inc. and DiaMedica Australia Pty Ltd. (collectively we, us, our, DiaMedica and the Company), exists for the primary purpose of advancing the clinical and commercial development of our proprietary recombinant KLK1 protein, DM199, for the treatment of neurological and kidney diseases. Currently, our primary focus is on developing DM199, a proprietary recombinant form of the human tissue kallikrein-1 (KLK1) protein for the treatment of acute ischemic stroke (AIS) and chronic kidney disease (CKD). Our parent company is governed under British Columbia’s Business Corporations Act, and our common shares are publicly traded on The Nasdaq Capital Market under the symbol “DMAC.” |

Notes to Financial Statements | |
Unusual Risks and Uncertainties [Table Text Block] | 2. Risks and Uncertainties DiaMedica operates in a highly regulated and competitive environment. The development, manufacturing and marketing of pharmaceutical products require approval from, and are subject to ongoing oversight by, the Food and Drug Administration (FDA) in the United States, the European Medicines Agency (EMA) in the European Union and comparable agencies in other countries. We are in the clinical stage of development of our initial product candidate, DM199, for the treatment of AIS and CKD. The Company has not completed the development of any product candidate and does not generate any revenues from the commercial sale of any product candidate. DM199 requires significant additional clinical testing and investment prior to seeking marketing approval and is not expected to be commercially available for at least three to four years, if at all. On July 6, 2022, the Company announced that the FDA placed a clinical hold on the Company’s Phase 2/3 ReMEDy2 trial, which is an adaptive design, randomized, double-blind, placebo-controlled trial studying the use of DM199 to treat AIS patients. The clinical hold was issued following the Company voluntarily pausing patient enrollment in the trial to investigate three unexpected instances of clinically significant hypotension (low blood pressure) occurring shortly after initiation of the intravenous (IV) dose of DM199. The blood pressure levels of the three patients recovered back to their baseline blood pressure within minutes after IV infusion was stopped and the patients suffered no further adverse events. The Company may not enroll any additional patients in the ReMEDy2 trial until the Company provides the FDA with the Company’s analysis of the events leading to or causing the hypotension, its protocol modifications to address the mitigation of these events, its rationale and supporting data for the protocol modifications, and the FDA notifies the Company that it may resume enrollment in the clinical trial. Based on information received to date, the Company believes that the use of IV administration bags made from a different type of plastic in the ReMEDy2 study is responsible for the unexpected hypotension and that a proportionate reduction in the DM199 dose level for the initial IV dose will effectively mitigate the hypotension issue in future ReMEDy2 patients. The Company plans to submit a revised ReMEDy2 trial protocol with the supporting rationale and data to the FDA in September 2022. However, there can be no assurance that our belief as to the cause of the hypotension events or our response to prevent future events is correct, or that we will be able to fully respond to the FDA’s questions sufficiently for the FDA to lift the clinical hold. It is also possible that the FDA may subsequently make additional requests that we would need to fulfill prior to the lifting of the clinical hold, such as requiring us to complete additional clinical trials or imposing stricter approval conditions than we currently expect for our DM199 product candidate. Prior to voluntarily halting enrollment, our Phase 2/3 ReMEDy2 trial has been adversely impacted by the COVID-19 pandemic and other factors. Specifically, we have experienced, and when we resume enrollment we may continue to experience, slower than expected site activations and enrollment in our ReMEDy2 trial. We believe this may be due to a number of factors, including the reduction or suspension of research activities at our current and targeted clinical study sites, as well as staffing shortages, due to COVID-19 and concerns managing logistics and protocol compliance for patients discharged from the hospital to an intermediate care facility during the three-week treatment period. While we are encouraged that COVID-19 related hospitalizations are down compared to prior periods and while we have taken and will continue to take certain actions to assist study sites in overcoming these issues, no assurances can be provided as to if and when these issues will resolve. The Company’s future success is dependent upon the success of its development efforts, its ability to demonstrate clinical progress for its DM199 product candidate in the United States or other markets, its ability to obtain required governmental approvals of its product candidate, its ability to license or market and sell its DM199 product candidate and its ability to obtain additional financing to fund these efforts. As of June 30, 2022, we have incurred losses of $89.4 million since our inception in 2000. For the six months ended June 30, 2022, we incurred a net loss of $6.9 million and negative cash flows from operating activities of $6.4 million. We expect to continue to incur operating losses until such time as any future product sales, royalty payments, licensing fees, and/or milestone payments generate revenue sufficient to fund our continuing operations. For the foreseeable future, we expect to incur significant operating losses as we continue the development and clinical studies of, and to seek regulatory approval for, our DM199 product candidate. As of June 30, 2022, DiaMedica had combined cash, cash equivalents and marketable securities of $38.4 million, working capital of $37.6 million and shareholders’ equity of $37.7 million. Our principal source of cash has been net proceeds from the issuance of equity securities. Although the Company has previously been successful in obtaining financing through equity securities offerings, there is no assurance that we will be able to do so in the future. This is particularly true if we are unable to resolve the clinical hold on our ReMEDy2 trial, if our clinical data is not positive or if economic and market conditions do not improve or further deteriorate. We expect that we will need substantial additional capital to further our research and development activities, complete the required clinical studies, regulatory activities and manufacturing development for our product candidate, DM199, or any future product candidates, to a point where they may be licensed or commercially sold. We expect our current cash, cash equivalents and marketable securities to fund our planned operations for at least the next twelve months from the date of issuance of these condensed consolidated financial statements. The amount and timing of our future funding requirements will depend on many factors, including the timing and results of our ongoing development efforts, including the duration of the current clinical hold, the rate of site activation and enrollment in our clinical studies, the potential expansion of our current development programs, potential new development programs, the effects of the COVID-19 pandemic, staffing shortages and other factors on our clinical trials and our operating expenses. We may require significant additional funds earlier than we currently expect and there is no assurance that we will not need or seek additional funding prior to such time, especially if market conditions for raising capital are favorable. |

Liquidity and Management Plans [Text Block] | 3. Summary of Significant Accounting Policies Interim financial statements We have prepared the accompanying condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (US GAAP) for interim financial information and with the instructions to Form 10-Q and Regulation S-X of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. These condensed consolidated financial statements reflect all adjustments consisting of normal recurring accruals which, in the opinion of management, are necessary to present fairly our consolidated financial position, consolidated results of operations, consolidated statement of shareholders’ equity and consolidated cash flows for the periods and as of the dates presented. Our fiscal year ends on December 31. The condensed consolidated balance sheet as of December 31, 2021 was derived from our audited consolidated financial statements. Certain prior year amounts have been reclassified to conform to the current year presentation. These condensed consolidated financial statements should be read in conjunction with our annual consolidated financial statements and the notes thereto. The nature of our business is such that the results of any interim period may not be indicative of the results to be expected for the entire year. Cash and cash equivalents The Company considers all bank deposits, including money market funds, and other investments, purchased with an original maturity to the Company of three months or less, to be cash and cash equivalents. The carrying amount of our cash equivalents approximates fair value due to the short maturity of the investments. Concentration of credit risk Financial instruments that potentially expose the Company to concentration of credit risk consist primarily of cash, cash equivalents and marketable securities. The Company maintains its cash balances primarily with two financial institutions. These balances generally exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk in cash and cash equivalents. The Company believes that the credit risk related to marketable securities is limited due to the adherence to an investment policy focused on the preservation of principal. Marketable securities The Company’s marketable securities typically consist of obligations of the United States government and its agencies and investment grade corporate obligations, which are classified as available-for-sale and included in current assets as they are intended to fund current operations. Securities are valued based on market prices for similar assets using third party certified pricing sources. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of shareholders’ equity in accumulated other comprehensive loss. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization or accretion is included in interest income. Realized gains and losses, if any, are calculated on the specific identification method and are included in other income in the condensed consolidated statements of operations. Available-for-sale securities are reviewed for possible impairment at least quarterly, or more frequently if circumstances arise that may indicate impairment. When the fair value of the securities declines below the amortized cost basis, impairment is indicated and it must be determined whether it is other than temporary. Impairment is considered to be other than temporary if the Company: (i) intends to sell the security, (ii) will more likely than not be forced to sell the security before recovering its cost, or (iii) does not expect to recover the security’s amortized cost basis. If the decline in fair value is considered other than temporary, the cost basis of the security is adjusted to its fair market value and the realized loss is reported in earnings. Subsequent increases or decreases in fair value are reported as a component of shareholders’ equity in accumulated other comprehensive loss. There were no other-than-temporary unrealized losses as of June 30, 2022. Fair value measurements Under the authoritative guidance for fair value measurements, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels defined as follows: Level 1 Inputs Level 2 Inputs Level 3 Inputs As of June 30, 2022, the Company believes that the carrying amounts of its other financial instruments, including amounts receivable, accounts payable and accrued liabilities, approximate their fair value due to the short-term maturities of these instruments. See Note 4, titled “ Marketable Securities Patent costs Costs associated with applying for, prosecuting and maintaining patents are expensed as incurred given the uncertainty of patent approval and, if approved, the resulting probable future economic benefit to the Company. Patent-related costs, consisting primarily of legal expenses and filing/maintenance fees, are included in general and administrative costs and were $90,000 and $68,000 for the six months ended June 30, 2022 and 2021, respectively. |

Lessee, Operating Leases [Text Block] | 9. Operating Lease We lease certain office space under a non-cancelable operating lease. This lease does not have significant rent escalation holidays, concessions, leasehold improvement incentives or other build-out clauses. Further this lease does not contain contingent rent provisions. This lease terminates on August 31, 2022 and we do not have an option to renew. This lease does include both lease (e.g., fixed rent) and non-lease components (e.g., common-area and other maintenance costs). The non-lease components are deemed to be executory costs and are therefore excluded from the minimum lease payments used to determine the present value of the operating lease obligation and related right-of-use asset. Our operating lease cost and variable lease costs were $32,000 and $ 26,000, Maturities of our operating lease obligation are as follows as of June 30, 2022 (in thousands): 2022 11 Total lease payments $ 11 Less interest portion — Present value of lease obligation $ 11 New office lease In June 2022, we entered into an agreement to lease approximately 6,000 square feet of office space in Minneapolis, MN, near our current office space. The lease commencement date is expected to coincide with the initiation of the lease term on September 1, 2022. The lease term is 65 months, expiring on January 31, 2028. The aggregate base rent due over the initial term under the terms of the lease agreement is approximately $ 608,000, 5-year |

Earnings Per Share [Text Block] | 11. Net Loss Per Share We compute net loss per share by dividing our net loss (the numerator) by the weighted-average number of common shares outstanding (the denominator) during the period. Shares issued during the period and shares reacquired during the period, if any, are weighted for the portion of the period that they were outstanding. The computation of diluted earnings per share, or EPS, is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued. Our diluted EPS is the same as basic EPS due to common equivalent shares being excluded from the calculation, as their effect is anti-dilutive. The following table summarizes our calculation of net loss per common share for the periods (in thousands, except share and per share data): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Net loss $ (3,358 ) $ (3,274 ) $ (6,866 ) $ (6,896 ) Weighted average shares outstanding—basic and diluted 26,443,067 18,786,157 26,443,067 18,776,461 Basic and diluted net loss per share $ (0.13 ) $ (0.17 ) $ (0.26 ) $ (0.37 ) The following outstanding potential common shares were not included in the diluted net loss per share calculations as their effects were not dilutive: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Employee and non-employee stock options 2,623,998 1,421,092 2,623,998 1,421,092 Common shares issuable under common share purchase warrants 265,000 265,000 265,000 265,000 Common shares issuable under deferred stock units 134,402 72,142 134,402 72,142 |
